I''ve built Xen with the latest hg source pull, and I am not able to boot domU on my x86_64 boxes using configurations and setups that have previously worked. Has something changed since late last week that would require a change in my domU configuration file? When creating DomU, I get the following error message: VFS: Cannot open root device "sdb2" or unknown-block(0,0) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) The file system for DomU is ext3, and I''ve made sure that it is built in xenU kernel.

To make the story more complete: during the DomU boot it hangs for a while on: Blkif frontend is using grant tables. xen_blk: Initialising virtual block device driver And then spits out: xen_blk: Timeout connecting to device!
