KVM Test result, kernel 5ca24d9.., userspace 120e0c8..

[Zhao, Yunfeng]

Hi,

This is today's KVM test result against kvm.git 5ca24d96dbc31d7018bc71e355f824f25b70316e and kvm-userspace.git 120e0c89ac05bdbe63aa83389f051e67af037968.
No new issue has been found. Save/restore still passes on IA32e host but fails on IA32 host.

Issues:
1. PAE host hanged on some platforms while booting guests
https://sourceforge.net/tracker/index.php?func=detail&aid=1849200&group_id=180599&atid=893831
2. Crashme causes RHEL5 guest kernel panic
The guest will kernel panic immediately after starting the test.

Retested it on KVM-57.
It has been fixed already.
Thanks a lot!

Actually, the fix is post kvm-57. What kvm-userspace.git commit did you
test?

The kvm-userspace commit is c41ab776181097efb6e6fbb5aa33b4a1f5df3d4f and 
kernel commit is 89075253714a299236b8debfbfdcb670a3932a1b.
I just noticed that the userspace is not kvm-57.

Thanks

Seems the issue is not fully resolved.
Save/restore on 64bist host may cause guest to kernel panic.
Here is the snapshot:
https://sourceforge.net/tracker/download.php?group_id=180599&atid=893831&file_id=259112&aid=1824525

And following error message will be found in dmesg:
