Cloudstack vm-snapshot is pausing the vm in the kvm. how to avoid this? even if we not enable the memory snapshot option still it is pausing. is there any alternative for this so that we dont need to pause the vm.

And how does the volume backup work? if we have multiple volumes for the vm's how to take backup and how to restore ?

@nsaikrishna15 , I think this is a libvirt limitation and we'll have to live with for now?

@nsaikrishna15 this issue could be avoided if you use 'qemu-kvm-ev' RPMs on the KVM.

I think there were some improvements, can you test 4.18.1.0 or 4.19.0.0 @nsaikrishna15 ?

nsaikrishna15 commented 7 months ago

Got to know that it's a limitation from KVM s We stopped relying on the vm snapshots and using storage level snapshots for the backup and restore. Thanks for the suggestions will try the new versions in next cycles.
