I tried this, but the domU still freezes up -- though it seems to be freezing at a different place now than it did previously. See the attached console output. This time, it froze on the third line from the end ("Setting the system clock.."); the last two lines of output happened after I did an "xm shutdown" on the domU. In case it matters, I'm trying to run Xen 3.1 on an Ubuntu 7.10 system (kernel = 2.6.22-14-xen). The hardware is an AMD Athlon XP 2700+ with 2 GB of RAM. The dom0 seems to run perfectly. -- Rich Wales === Palo Alto, CA, USA === richw@xxxxxxxxx http://www.richw.org === http://en.wikipedia.org/wiki/User:Richwales
