Re: Snapshots on KVM corrupting disk images

[cloudstack-fan]

Dear colleagues,

Have anyone upgraded to 4.11.3? This version includes a patch that should help 
to avoid encountering with this problem: 
https://github.com/apache/cloudstack/pull/3194. It would be great to know if it 
has helped you.

Thanks in advance for sharing your experience.

Best regards,
a big CloudStack fan :)
