hi,
i tried to attach a LVM volume to a running guest:
xm block-attach vm01 phy:/dev/daten/vm01-daten /dev/sdb1 w
but in the guest nothing happens.
rohan:~# xm block-list vm01
Vdev BE handle state evt-ch ring-ref BE-path

2065 0 0 4 10 597 /local/domain/0/backend/vbd/3/2065
the log shows:

If it''s a para-virtual guest I expect it to work. The reason is that the HVM guest most likely doesn''t have a para-virtual driver that reads the xenstore to realize that there is a new device there. -- Mats> > cu denny > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] [3.0.3] block-attach does not work *SOLVED*
