Important Considerations

Upgrading to Release 7.8.0.0

Upgrade to everRun Release 7.8.0.0 following the upgrade path for the release that is running on your system, as listed in the table below.

Release Upgrade Path

Releases 7.7.0.0, 7.6.1.0, 7.6.0.0, 7.5.1.1, 7.4.3.2

Upgrade directly to Release 7.8.0.0 following instructions in Upgrading everRun Software Using an Upgrade Kit.

Releases 7.5.1.0, 7.5.0.5, 7.4.3.0, 7.4.2.0, 7.4.1.0, 7.4.0.0, 7.3.4.0

Upgrade to Release 7.6.1.0 first, and then upgrade to Release 7.8.0.0. For information on upgrading to Release 7.6.1.0, see the everRun Release 7.6.1.0 Release Notes and Help.

Releases 7.3.2.0 and earlier

Upgrade to Release 7.3.4.0 first, then to Release 7.6.1.0, and finally to Release 7.8.0.0. To upgrade to Release 7.3.4.0, see the everRun Release 7.3.4.0 Release Notes and Help.

During Upgrade, Refresh Browser and Accept New Certificate

During an upgrade to Release 7.8.0.0, the browser may display the upgrade as stalled after the first node has been upgraded and become the new primary node. This incorrect browser display can occur if the browser has a new certificate from Stratus that needs to be accepted. You should refresh the browser and, if prompted, accept the new certificate. After you have accepted the new certificate, the browser displays the correct status of the upgrade.

Tested Guest Operating Systems

For a list of the guest operating systems tested with the current release, see Tested Guest Operating Systems.

Known Issues

Installation of VirtIO Serial Driver Fails After a Windows 2008 (SP2, 32-Bit) VM Is Created

After a Windows 2008 SP2 (32-bit) VM is created, the installation of the VirtIO serial driver fails. In this situation, you must install the driver manually. To do so, download the VirtIO ISO file from the Downloads page at https://www.stratus.com/services-support/downloads/?tab=everrun. Continue by following instructions in Updating the VirtIO Drivers (Windows-based VMs), though selecting the serial driver (vioser). Note that this problem does not occur with the 64-bit version of Windows 2008 SP2.

Guest Performance Issues with Large Guest Volumes

Guest volumes that are 2TB or greater in size and that become fragmented over time may significantly reduce guest performance. When volumes of this size are created, Stratus recommends that qcow2 be selected as the disk image format. The format qcow2, instead of raw, reduces performance slightly, but prevents the significant performance reduction seen with raw guest volumes of this size. For information on creating guest volumes, see Creating a Volume in a Virtual Machine.

Removable Media and Migrating a PM or VM Using the P2V Client

Before migrating a PM or VM using a bootable P2V client (virt-p2v) ISO file, check if any removable media (for example, floppy disks, DVD drives, or external USB disks) are attached to the source image. If removable media are attached to the source image when you attempt to migrate a PM or VM, the error message Conversion failed appears. So, deselect the media in the virt-p2v window before starting the migration. To do so, access the virt-p2v window with the sections Target properties and Fixed hard disks, and then beneath Fixed hard disks, uncheck the box in the Convert column next to the removable media. See Migrating a Physical Machine or Virtual Machine to a System, particularly the section To migrate a PM or VM to the ztC Edge system, for more information on using virt-p2v.

W2K16x64 VM Console Is Lost After Upgrade From Release 7.4.3

When a system running everRun Release 7.4.3.x has a VM running Windows Server 2016 with an open console session, and you upgrade the system to Release 7.8.0.0, the console session displays Guest has not initialized the display (yet) and cannot open correctly. To correct the problem, shutdown and then restart the VM, and re-open the console session.

Maximum Path Length When Importing a VM

When you import a VM using the Import/Restore Virtual Machine wizard, the maximum length of the path to the VM, including the VM name, is 4096 characters for the import options Import from remote/network Windows Share(CIFS/SMB) and Import from remote/network NFS.

Importing an OVA File Sometimes Fails

If you begin to import an OVA file and then the node is placed into maintenance mode or loses power, the OVA import fails, and any future attempt to import an OVA file fails. For information on a work-around for this problem, see KB-10035.

After Importing a Linux VMware OVA File, Manually Configure Network Information

Importing a Linux VMware OVA file changes the network interface and networks-scripts file. After you import the file, you need to manually configure the network information using the following procedure:

  1. On the Virtual Machines page, select the VM.

  2. Click Console in the bottom panel to open the VM login page (for additional information, see Opening a Virtual Machine Console Session).

  3. Login into the VM.

  4. Open a command prompt window.

  5. Issue the ifconfig command. In the command output, check if ip address is assigned to the virtual network interface eth0.

  6. If ip address is not assigned to eth0, list the contents of the /etc/sysconfig/network-scripts directory.

  7. Note the value of ifcfg-xxxx (though not ifcfg-lo).

  8. Rename ifcfg-xxxx to be ifcfg-eth0.

  9. Edit the ifcfg-eth0 file, changing the values of DEVICE and ONBOOT, as follows:

    DEVICE=eth0
    ONBOOT=yes

    Save the file.

  10. Issue the following command to restart network services:

    systemctl restart network
  11. Verify the IP assignment by issuing the command ifconfig. In the command output, confirm that ip address is assigned to eth0.

"Import from USB" Search Lists OVA Files in Various Directories

When you select Import from USB in the Import/Restore Virtual Machine wizard to import an OVA file, you can enter a file name or partial file name in the Search Files box. The box lists OVA files that have names matching the name entered in the box, and that reside in various directories:

For complete information on importing an OVA file, see Importing an OVF or OVA File.

Cannot Import RHEL 8.1 VMs

You cannot import a VM running RHEL 8.1 (with BIOS boot firmware) from a VMware ESXi 6.7.0 server to a everRun system.

Storage Group Size is Zero After PXE Recover or PXE Replace

You can recover or replace a PM from a temporary Preboot Execution Environment (PXE) server on the primary PM. After the procedure is complete, the Size Available, Size, and Size Used columns of a Storage Group display zero in all three columns, with the following selections in the PXE procedures:

This is a display problem. The actual size in the system is accurate. To correct the display, re-assign the disk to the storage group.

Maximum Resolution of a UEFI VM Console Session

On the Virtual Machines page of the everRun Availability Console, you can open a VM console session to display the console of the guest operating system running in the VM. When you open a console session to access a guest VM with a UEFI boot type, the console session has a maximum resolution of 800x600. For a higher resolution, connect to the VM using a Remote Desktop Connection.

Restart VMs for vmgenid Support

After a system is upgraded from Release 7.6.1.0 (or earlier) to Release 7.8.0.0 using an upgrade kit, support for vmgenid on VMs running Windows Server 2019, Windows Server 2016, or Windows Server 2012 is not present until after the VMs are restarted. Therefore, you must restart such VMs to enable vmgenid support after the upgrade. If you are upgrading from Release 7.7.0.0, you do not need to restart such VMs if they had previously been restarted on the system running Release 7.7.0.0.

Creating VCD fails when console browser is Microsoft Edge

When you are using Microsoft Edge as the browser for the everRun Availability Console you cannot create a VCD: the process will fail. Instead, use another compatible browser (see Compatible Internet Browsers).

To import a VMware VM, Use OS Shutdown Commands

When importing a VMware VM, you must shutdown the VM using operating system shutdown commands in addition to powering it off from the VMware console. If you shutdown the VM using only the VMware console, the import will fail.

Mapping of Japanese Keyboards 106 and 109 For Console in IE10, IE11, or Firefox May Be Incorrect

The mapping of the Japanese keyboards 106 and 109 may be incorrect when using IE10, IE11, or Firefox to access the everRun Availability Console. Use Chrome or remote connection software (VNC or RDP), instead.

VMs Running Windows 2016 with the Maximum vCPUs and Memory Will Not Reboot Cleanly

A Windows 2016 VM with the maximum supported number of vCPUs and the maximum amount of memory will not reboot cleanly. To avoid the problem, reboot the VM using the Shutdown button (on the *Virtual Machines* page, in the bottom pane for the VM), and then restart the VM using the Start button. To avoid the problem, reduce the number of vCPUs or the amount of memory assigned to the VM.

Some Browsers Unable to Connect a VNC When Using https

If you are connected to the everRun Availability Console using an https URL in a Microsoft Internet Explorer or Mozilla® FireFox® browser, and you click Console after selecting a running VM from the Virtual Machines page, the message VNC: Unable to connect, retrying in n seconds may appear. To enable the VNC connection, click the https link to the VNC console page in the upper right-hand corner of the masthead, and continue with the appropriate procedure below (procedure in your browser may differ, depending on the version of your browser):

The VNC console appears.

Removing Snapshots Temporarily Prevents Some VM Operations

When you remove a snapshot on an everRun system, the system must coalesce the snapshot by merging it with the next oldest snapshot. While the system is coalescing snapshots:

Avoid removing snapshots if you have an immediate need to perform any of these operations. After you remove a snapshot, wait at least 10-15 minutes before attempting any of these operations, or retry the operation if needed. You may need to wait much longer depending on the size of your volumes, the amount of VM activity, and the number of snapshots you remove.

For information about how to monitor coalescing operations that are underway, see KB-4272.

Application-consistent Snapshots of Windows 2008 and Windows 2003 VMs Fail

The system cannot create application-consistent snapshots of VMs running Windows 2008 (32 bit) and Windows 2003 (32 bit). The system can create only crash-consistent snapshots of VMs running these operating systems.

Reboot Required when Changing Node IP Address or Netmask Network Settings

When you change the IP address or netmask settings of a node as described in Configuring IP Settings, both the old and new settings are in effect until you reboot the node. Having both settings active may cause routing or connection issues.
