[chetan sonawane]

Hello Team,

After restarted hostnode one of the windows kvm vm disk showing one year back data.

last year,This vm initially restore from proxmox backup file. But we are not able to trace how come this vm data change to last state. There is no snapshot created for this.

Before shut down hostnode this vm disk was change with write-back option. this is only changed we have made for this vm.
