Dear XEN expert：
We meet some problem in our project: In our previous project, we use KVM, and we do some job like this:
We create KVM snapshot by “virsh snapshot-create $DomainName $SnapshotXml”, then do following job:
While(1)
{
Run “virsh snapshot-revert $DomainName $Snapshot --running --force”
Do some job in 30 secends
}
Now our project is move to Xen, so we need to do same thing like in KVM, but we found that there is no “Snapshot” in xen , so we change the job like this in xen:
While(1)
{
Run “xl destroy win7_checkpointFile”
Run “xl restore win7_checkpointFile”
Do some job in 30 secends
}
We found that” xl destroy “and “xl restore” spend 10 times longer than “virsh snapshot-revert”, it is unacceptable in our project
So our question is that: Is there a faster way to restore Virtual machine status in Xen?
Our environment:
CPU: intel xeon E52620 2.40GHz with 24 core,
memory : 256G,
SSD hard disk.
Host machine: suse12
xen_version: 4.8.2
The VM is Win7 OS with 2G memory
Best regards
