I suspect what is happening is that the new guest OS kernel is exiting for some reason. The most likely reason is that it can't mount its root partition. I assume your sda7 contains a valid root file system i.e. you can mount sda7 from domain0 OK? [NB: make sure the filesystem is unmounted before trying to mount it from another domain!] Normally, the control tools would let you see the console output from the domain and you could see what's going on. It looks like you're hitting multiple bugs in the new tools -- Mike is best placed to try and interpret the various back traces as I don't know my way around the new code yet. BTW: Thanks for bearing with us while we complete this major bit of integration work to the xeno-unstable tree. I think things will have settled down substantially by the end of next week, proving you guys keep beating on it and telling us about the bugs ;-) Ian > xen1:~# xm create -f /etc/xc/sbssgw1 -Dvmid=1 >
