[Xen-ia64-devel] A strange issue when VTI guest vcpus number is near pcpus
Hi, When I try recently Xen (Xen 3.4 rc3) on IA64 machine (Tiger4), I found some strange issue. My two systems have 4 and 8 pcpus separately If VTI guest's vcpus is near pcpus, guest booting will meet some issues: 1. Guest boot might be hang at switch to new root and run init; unmounting old /dev ...; unmounting old /sys for a long time. 2. After guest boot up, it might report illegal instructions for command or report readonly filesystem. I didn't catch it in UP or 2 vcpus conditions. Looks a qemu issue? Did you meet it also?

If I double vcpus ( 2*pcups), this issue is more easy to happen. I didn't try multi guest yet.
