Yes, I've tried the ttylinux right now, it starts the instance, but it booted up a busybox, probably a recover from initrd (see output in the end of this e-maill). I can access the instance by doing a xl console in the host, describe-instances shows the status "running test".
I've successfully booted a separated vm with an old image I used with Xen with Xen + libvirt just changing the openstack's libvirt.xml. It just works fine. The instance dir in /var/lib/nova/instances files look like this: 0 -rw-r----- 1 nova nogroup 0 2011-09-28 15:43 console.log 15M -rw-r--r-- 1 nova nogroup 18M 2011-09-28 15:43 disk 4,3M -rw-r--r-- 1 nova nogroup 4,3M 2011-09-28 15:43 kernel 4,0K -rw-r--r-- 1 nova nogroup 1,3K 2011-09-28 15:43 libvirt.xml 5,7M -rw-r--r-- 1 nova nogroup 5,7M 2011-09-28 15:43 ramdisk this is the last output I get when I get into the instance console: [ 0.078066] blkfront: sda: barriers enabled [ 0.078394] sda: unknown partition table [ 0.170040] XENBUS: Device with no driver: device/vkbd/0 [ 0.170051] XENBUS: Device with no driver: device/vfb/0 [ 0.170056] XENBUS: Device with no driver: device/console/0 [ 0.170074] Magic number: 1:252:3141 [ 0.170114] /build/buildd/linux-2.6.35/drivers/rtc/hctosys.c: unable to open rtc device (rtc0) [ 0.170122] BIOS EDD facility v0.16 2004-Jun-25, 0 devices found [ 0.170127] EDD information not available.
