Aaron, Seems to be something related to your block device. Try this config file: name = "Belldandy" maxmem = 256 memory = 256 vcpus = 1 builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" device_model = "/usr/lib64/xen/bin/qemu-dm" disk = [ "phy:/dev/SystemsVG/Belldandy,hda,w" ] vif = [ "mac=00:16:3e:1d:43:df,bridge=xenbr0,script=vif-bridge" ] vncpasswd='YOURPASSHERE' vnclisten="YOURDOM0 IP HERE" vnc=1 Using one of this options: disk = [ 'phy:/dev/SystemsVG/Belldandy, ioemu:hda,w' ] disk = [ 'phy:/dev/SystemsVG/Belldandy, sda,w' ] disk = [ 'phy:/dev/SystemsVG/Belldandy, xvda,w' ] You can try comment your vif line, maybe is something related to it, and it won't start. Then, try to connect to vnc server: dom0ip:5900 What's the difference between yours domU config files ? Did you see any other error in xend.log ? If there is no difference at all, try to fsck your lvm partition. 2010/3/29 Aaron Clark <ophidian at ophidian.homeip.net> > On 03/29/2010 09:37 PM, Christopher G.
