HP Insight Control Virtual Machine Management 6.0

Copied or moved Xen virtual machine guest does not start on the destination host
When a Xen virtual machine guest is copied or moved to another host, Insight Control virtual machine
management attempts to convert the Xen bridge of the guest to match a bridge present on the destination.
When trying to start the virtual machine guest, the following error appears on the console:
Error: Device 0 (vif) could not be connected. Could not find bridge device
xenbr<#>
To resolve this issue, modify the configuration of the virtual machine guest to use an existing Xen bridge on
the destination system.
1. List the existing bridges on the destination host using the command brctl show. If no Xen bridges
are created, create one with the /etc/xen/scripts/network-bridge script.
For example: /etc/xen/scripts/network-bridge start netdev=eth0 vifnum=0
2. Dump the Xen virtual machine guest XML configuration to a file: virsh dumpxml GUEST_NAME >
guest.xml
3. Undefine the Xen virtual machine guest on the system: virsh undefine GUEST_NAME
4. Modify the Xen bridge in the configuration by editing the <source bridge='> XML tag.
5. Redefine the Xen virtual machine guest on the system: virsh define guest.xml
6. Start the Xen virtual machine guest.
Handle virtual machine host prefailure events task does not progress
For VMware ESX 3. x or VMware ESX 3. x hosts, when Deploy→Virtual Machine→Handle VM Host
Prefailure Events is selected, the virtual machine host is placed into maintenance mode in VMware vCenter
Server. To enter maintenance mode, all virtual machines must be powered down or migrated to other virtual
machine hosts. Manual intervention might be required to complete this task.
HTTP ERROR: 500 Internal Server Error message appears during a Insight
Control virtual machine management move or copy operation
This error can occur when the network is busy during the move or copy operation.

Insight Control virtual machine management cannot move virtual machines with certain
disk types
Insight Control virtual machine management does not move or copy virtual machines with the following disk
types when installed with the indicated virtualization technology.
Unsupported disk types include the following:
• Linked disk
• Differencing disk
• Physical (RAW) disk
Virtual machine files are not deleted after a move
Insight Control virtual machine management does not delete virtual machine guest files after a move, enabling
the virtual machine guest to be restored on the source host. This scenario occurs only with Xen virtual machine
hosts not in other hypervisors.
Virtual machine devices might not be available after a copy or move
Reconfigure the virtual network connections on the moved or copied virtual machine guest.
A shutdown or restart operation fails or does not complete
You must install VMware Tools on virtual machine guests before you can perform a shutdown or reset.
To install Microsoft Virtual Server Additions or VMware Tools, see the HP Insight Software Installation and
Configuration Guide .
