HP Insight Control Virtual Machine Management 6.2 User Guide

Error message Unknown to VMM appears when performing the copy operation on

a virtual machine

If the error message Unknown to VMM appears when performing the copy operation on a virtual machine,

ensure that the virtual machine exists on the host. If the virtual machine has been deleted from the host, but

the virtual machine node is still present in Systems Insight Manager, run the Identify Systems task on the

virtual machine host from Options→Identify Systems in Systems Insight Manager. If the virtual machine

was manually discovered in Systems Insight Manager using the IP address, then the virtual machine must be

deleted from the Systems Insight Manager All Systems page.

Transport operation fails after restarting virtual machine management

If you restart virtual machine management after initiating the transport operation, the transport operation

will fail. However, the result of the transport operation on the virtual machine host is hypervisor-dependent.

This might require removing unwanted resources such as virtual machine files and disks on the hypervisor.

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, 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.

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.
