If the virtual machine guest being restored exists on the selected host, then one of the following must occur: • If a virtual machine guest with the same BIOS ID exists on the virtual machine host and is located in the folder to where the backup is to be restored, then you must stop the existing virtual machine host. Existing files are overwritten. • If a virtual machine guest with the same BIOS ID exists on the virtual machine host and the restore location is different, then you must unregister the existing virtual machine host. The restore folder must be empty before you restore the backup. • If a virtual machine guest with the same BIOS ID exists on a different virtual machine host, then a warning appears. The restore folder must be empty before you restore the virtual machine guest.

Restoring the most recent virtual machine guest backup
NOTE:
For Xen on RHEL or SLES, you cannot restore most recent virtual machine backup.
Virtual Machine Management Pack enables you to restore a virtual machine guest using the last backup
created. When you perform the following procedure, the most recent backup is restored to the virtual machine.
1.
On the
HP SIM All Systems

Recovering virtual machines of a failed host on a VMware ESX Server or HP integrated
Citrix XenServer
Alternate virtual machine host information in the Virtual Machine Configuration Details table is retained after
recovery of a failed virtual machine, and you can manually delete the information.
Recover virtual machines of a failed host to move all enabled virtual machines from a specified failed host
to defined recovery servers.
To recover a virtual machine of a failed host:
1.
If the virtual machines remain on the recovery servers, then you must set a new alternate virtual machine
host. For more information, see the
Setting an alternate virtual machine host on a VMware ESX Server
or HP integrated Citrix XenServer
section.
2.
On the
HP SIM All Systems
page, select the failed VMware ESX Server virtual machine host.
3.
From the HP SIM toolbar, select
Deploy
→

→
Recover Virtual Machines of Failed
Host.
4.
To recover the virtual machine now, click
Run Now
, or to perform the recovery later, click
Schedule
.
When you schedule VMM tasks, the Schedule option in HP SIM does not work reliably because Virtual
Machine Management Pack might not be activated when HP SIM is activated.
Scheduled tasks are evaluated every minute. The maximum time delay between the scheduled time of
an event and when the event is performed is 59 seconds.
Setting an alternate virtual machine host on a VMware ESX Server or HP integrated
Citrix XenServer
You must store all virtual disks for the virtual machine on a SAN-based VMware file system.
IMPORTANT:
The failover host must have access to the VMware file system where the virtual machine
virtual disks are stored.
Specifying an alternate virtual machine host for a virtual machine enables you to select a recovery server
for one or more virtual machines.
