So something must be going wrong there. Here's the function it uses in libvirt code: http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/xen/xen_hypervisor.c;h=b5b2328c22ccffb17f7710b3ed6064907d744215;hb=HEAD#l2563 Something must be funky or unexpected with /sys/hypervisor/properties/capabilities > I manage the VMs using my local laptop, running latest Archlinux and > latest virt-manager. > > blackie% uname -a > Linux blackie 3.2.2-1-ARCH #1 SMP PREEMPT Thu Jan 26 08:40:20 CET 2012 > x86_64 Intel(R) Core(TM)2 Duo CPU T6670 @ 2.20GHz GenuineIntel > GNU/Linux > blackie% libvirtd --version > libvirtd (libvirt) 0.9.9 > blackie% virt-manager --version > 0.9.0 > > Another perhaps related issue: when I try to provision through > virt-install, I always run into this: > > blackie% virt-install --connect xen+ssh://root@lux-002 > ERROR Must be root to create Xen guests > blackie% virt-install --version > 0.600.0 > That's a virt-install bug fixed in 0.600.1 which was released a couple days ago. Probably won't solve your 'no install options' problem though. - Cole
