I've tried multiple upgrades from 6.3-20120509.1 to 6.3-20120516.0 and have not seen the "Failed to Establish Libvirt Connection" error yet.  Can you provide log files?  Exact Steps?  What setup was done on the old version prior to upgrading?

Hi Mike,

For the libvirtd.log, see comment #4. I also try to upgrade rhev-h from 6.3-20120502.3 to 6.3-20120509.1 without such libvirt connection error, while the upgrade of 6.3-20120509.1 to 6.3-20120516.0 will show this error every time. The steps of upgrade are shown below:

1. TUI install the older rhev-h to local disk
2. boot and check whether the installed rhev-h can boot normally
3. pxe boot to the new rhev-h to upgrade with TUI
