Can you take this one? I hit this recently on SLES 10 SP1 beta 2, using 64 bit hypervisor and running xenpae dom0. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

According to #2, I take it that using a 32-bit vs. a 64-bit hypervisor doesn't matter? Any relevant messages on the dom0 side, or from Xen? (I have no problem booting a pre-existing [originally using blkback] SLES10 GA domain [optionally with SP1 kernel] via tap, on an 8G box running 3.0.4 and SP1 dom0.) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
