Bug 649673

Hi Yuwen, please test this bug on RHEL5.5 GA xen kernel to see if it reproduces

Reproduced on RHEL5.5 GA everytime.
Error: could not start the FV Guest.

# virsh start v7ia64
error: failed to get domain 'v7ia64'
error: Domain not found: xenUnifiedDomainLookupByName

The error is different from that of RHEL5.6.
In RHEL5.6, FV Guest can start but run fail as attachment.

Last tests are on system without HVM support.

On system with HVM support, the error of RHEL5.5 GA is the same as RHEL5.6.

Platform: system with key/value HVM=1.
OS: RHEL5-Server-U5_nfs-ia64
V7: 1.2-25

Find in virsh console log that guest use out swap.

> Find in virsh console log that guest use out swap.

I found that, too. Tested on an ia64 machine with 20G swap but the test ate them up all.

Please attach /var/v7/results.xml.  Also, what guest and data images are being used?

Why did the "records" change from 16384 to 11264? Memory leak?

I suspect the swap partition in your image is not set up correctly.
