Re: [libvirt-users] VM Performance using KVM Vs. VMware ESXi
About Spice: I think it’s good practice to use spice because it improves the
performance of the VM in general by improving screen performance. If your VM is
constantly displaying output, you’ll probably will notice a difference.
About virtio: You can see it in the settings. Better yet, it’s in your XML. If
you post your XML, we can take a look…

Dear Jatin,
Maybe it’s a good idea first to implement Spice:
<video>
<model type='qxl' ram='65536'
vram='65536' heads='1'/>
<address type='pci'
domain='0x0000' bus='0x00' slot='0x02'
function='0x0'/>
</video>
<channel type='spicevmc'>
<target type='virtio'
name='com.redhat.spice.0'/>
<address type='virtio-serial'
controller='0' bus='0' port='1'/>
</channel>
Spice should be installed on the host.
[Jatin] How will using Spice help in improving better response time from a web
application that i am using inside a VM ? Can you throw more light in this
regard if it helps in improving the response time.
Do you use virtio ?
[Jatin] I am not sure about this. Can you tell me how can i find out if i am
using virtio or not ?
Greetings,
Dominique.
Thanks
