hi,
i tried lvm (vers. 1) with xenU 2.4. i created one group on a raid0-device
/dev/md/0 (devfs with gentoo) with several lv's for swap and root for virtual
hosts. on xen0 i can mount and use these devices without any problem, one of
these device is currently used as swap for xen0.
i tried to give access with this xmdefaults configuration
(not mounted in vm as root like the name says, only access for later
test-mount):
disk = [ 'phy:hdb5,hdb5,w' , 'phy:hda6,hda6,w' ,
'phy:/dev/vg0/rootvm101,hdx1,w' ]
before:
disk = [ 'phy:hdb5,hdb5,w' , 'phy:hda6,hda6,w' ]
when trying to start the vm, this error occurs (i modified xmdefaults to accept
vmid=vm101 like the name of the vm):
root@vm0 vm # xm create -c vmid=vm101
Using config file /etc/xen/xmdefaults
Error: Error creating domain: [Failure instance: Traceback:
xen.xend.XendError.VmError, vbd: Segments not found:
uname=phy:/dev/vg0/rootvm101
the xend-log says following while creation:
[2004-08-07 12:14:15 xend] DEBUG (XendDomainInfo:692) init_domain> Created

dom=14
i also noticed that changing configuration to
disk = [ 'phy:hdb5,hdxSWAP,w' , 'phy:hda6,hdxUSR,w' ]
produces also an error like:
Using config file /etc/xen/xmdefaults
Error: Error creating domain: [Failure instance: Traceback: <type 'tuple'>,
(<twisted.python.failure.Failure exceptions.TypeError>, 1)
output in xend-log is the same.
any hints for this? or is lvm 1 generally not supported which means i have to
patch?
thanks & best regards,
bjoern
