Citrix has released hotfix 12 (XS610E012) for XenServer 6.1.0 today.
This hotfix resolves the following issues:
- If a Virtual Machine (VM) running on a pool member is shut down when the XAPI service is not running, the associated Virtual Disks Images (VDIs) do not get detached.
- After shutting down a VM, attempts to immediately destroy a Virtual Block Device (VBD) attached to the VM will fail. This is due a race condition which marks the VBD as attached – even when the VM is shut down.
- When the Pool Master is unavailable, attempts to restart the XAPI service on a pool member can result in a failure to set up the management interface.
- Shutting down a VM after optimizing it for XenApp environment, either through the Advanced Options in XenCenter or by using the xe Command Line Interface, can cause the Optimize for Citrix XenApp setting to revert.
- Attempts to migrate a VM over an intermittent network connection can cause the migration process to fail and result in deadbeef domains (that is, domains which cannot be terminated). This is due to incorrect TCP timeout values set on the file descriptor used for migration. When this happens, the affected domains will be listed as deadbeef in the output from the list_domains command.
In addition, this hotfix also includes the following previously released hotfixes.
