I''m getting the following error when I try and create a new domain. Using config file "/etc/xen/db1". Error: Error creating domain: vbd: Segment not found: uname=phy:fs/db1 However, if I reset the machine, this problem appears to go away for a time, only to be replaced with another. The domain is started, but in the log files it is noted that it is restarted over and over until xend complains that it''s been restarting too fast and stops trying. The last succesful log entry mentions attempting to connect the event channel. After this the domain is restarted. Any help with either of these issues would be greatly appreciated, I can give plenty more details if needed.

Re: [Xen-devel] Cannot create domain with lvm rootfs
Hi there,> Using config file "/etc/xen/db1". > Error: Error creating domain: vbd: Segment not found: uname=phy:fs/db1* Can you confirm the device node is really present before and after the failure to start the domain? * Can you mount the device in domain 0 before and after the failure to start the domain?> However, if I reset the machine, this problem appears to go away for a > time, only to be replaced with another. The domain is started, but in the > log files it is noted that it is restarted over and over until xend > complains that it''s been restarting too fast and stops trying.Sounds like Xend is finding the VBD device node when building the domain but that the domain kernel is bailing out for some reason after being started. Given your other problems, I''d speculate it can''t mount its root filesystem and so is repeatedly rebooting. * Can you capture the boot output for this domain? Specify the -c flag to xm to make it turn into the domain console. With luck the domain will tell us what''s wrong... * Does the original problem ever come back after a reboot?

At the moment, it appears I''m having a problem with LVM2. /dev/fs/db1 is a symlink to /dev/mapper/fs-db1 which doesn''t exist. lvs list''s all of my logical volumes correctly, but it appears that the kernel isn''t aware of them.>* Can you capture the boot output for this domain?
