Hi, I'm Using RHEV 3.3 angetting below error while importing VM image from export doamin.

Comment 1 Allon Mureinik 2014-05-10 10:01:36 UTC 
thirupathi, can you please attach engine and VDSM logs?
Comment 2 thirupathi 2014-05-10 10:11:17 UTC 
Created attachment 894232 [details]
engine.log

Here I attached the logs from Rhev Manager.
Pls help to check. I was getting error while removing the VM in export domain and got the status VM removed from export domain but the VM still there.
You can see in logs.

Thanks,
Thirupathi
Comment 3 thirupathi 2014-05-10 10:20:10 UTC 
I think the error is because of Permission at export domain path on manager.
[root@nocrhevm01 images]# pwd
/exports/migrate/63a269c0-2fa6-4705-b617-2af2f174de34/images

drwxr-xr-x. 2 vdsm kvm  4096 Apr  7 15:49 43182df3-97c3-4642-98fb-f372af8cbb04
drwxr-xr-x. 2 vdsm kvm  4096 May 10 14:50 53d3a77a-b765-487f-950a-21db75ec5048

drwxr-xr-x. 2 root root 4096 May  9 17:17 c8ceded2-3e28-4076-ae4a-f3fa8ca523c6

I'm able to import the VM's if images Permission vdsm:kvm only.
I'm not able to import the VM's if images Permission root:root.
Can I ask why its like that ?

2. I have done P2V, the server was on IBM hardware and It was using LVM but after conversion VM got all standard partitions instead of LVM. Why ? 
Is it normal or abnormal ? I want the converted VM should be in LVM.

Thanks,
Thiru
Comment 4 Maor 2014-05-10 21:29:28 UTC 
files under /exports/migrate/63a269c0-2fa6-4705-b617-2af2f174de34/images should be all vdsm:kvm. The bug here is that the files  9b85767a-a7a7-4648-a6a6-3b6de20c1b67 and c8ceded2-3e28-4076-ae4a-f3fa8ca523c6 has been created with the root permissions.

Can you reproduce this (creating files with root permissions) on other VMs? Is it always happens when you do P2V? What is your P2V version?
Can u also attach the VDSM logs with the file creation logs?

After three months of inactivity, closing.
thirupathi, if you have a reproducer with the logs Maor requested, please reopen and attach them.
