Drivers
Hi Guys
I run KVM node via Cloudstack, and want to confirm if there are any
additional guest agents & drivers that I need to install to my guest VM?
For both Linux and Windows guests?

Hi,
`*kvm.vmstoragesnapshot.enabled` *requires only qemu-guest-agent. It is
used to freeze/thaw the virtual machine during snapshotting - VM snapshots
without memory
<https://docs.cloudstack.apache.org/en/latest/adminguide/virtual_machines.html#storage-based-vm-snapshots-on-kvm>
Best regards,
Slavka

Hi Nux
That sounds great. For what it's worth, I did find the following
setting in global config:
*kvm.vmstoragesnapshot.enabled*: For live snapshot of virtual machine
instance on KVM hypervisor without memory. Requieres qemu version 1.6+
(on NFS or Local file system) and qemu-guest-agent installed on guest VM
So it seems it does use qemu-ga to some sort.

Hi,
Make sure you have the virtio drivers installed.
Linux has them by default, but Windows opted not to have support for it,
so you will have to do it for them.
If you do not use virtio devices (ie paravirt) your IO will suffer.
