when execute backup job on ubuntu VM,the backup job failed.
check the view log,the create snapshot failed and execution backup job failed.
Backup job failed.tr again later.
1.in customer environment,only tao ubuntu VM exist this issue,the another windows VM don't have this issue.we doubt this issue compatibility issue,so check the product document.
we found the snapshot just support One core VM.
but customer create the ubuntu VM is a 4 cores VW,
snapshot only support one core VM for unbuntu OS,if you create more than one core.VM will restart and hang when execution backup job。
change the VM from 4 core to 1 core.issue solved.
