Hi folks, I am testing Xen unstable and now run into unexpected difficulties with lvm support. I have started with the source this time and have compiled lvm support into the domU kernel. But when I start the domU the vbd driver cannot connect to the configured volumes. I have tried those syntaxes: disk=[''phy:/dev/lvmvol01/testhost-boot,sda1,w'' ...] disk=[''phy:lvmvol01/testhost-boot,sda1,w''...] since I found both in different places. lvmvol01 is the lvm volume group I am using. The error the vbd driver names is "error -22". The domU crashes since it cannot mount a root fs. Any hint or help is appreciated.

Are you sure lvm is the right place to look for the cause ? As far as I can grasp from the above, you are just exporting lvm volumes from dom0 to domU which will see a normal SCSI block device /dev/sda1 (at least you are using the exact same syntax as I am in Xen 2.0.6 stable). You don''t need an LVM driver in domU for that.> The error the vbd driver names is "error -22". The domU > crashes since it cannot mount a root fs.There is another thread titled "xenU vbd error -22" - perhaps that will bring you further than trying to find an lvm cause ?

One more thing: If it makes sense for the developpers to have one more person complaining I would of course go on testing unstable. It is not only my own business that counts. :-) Dirk Dirk H.

I actually switched all my testing exclusively to use slices for all media access. Running xm-test is useful, caution though :-) http://static.danplanet.com/xm-test/xm-test-0.2.0.tar.gz Regards, Ted _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
