[Xen-users] Error: Device 2049 (vbd) could not be connected. Path closed or removed during hotplug add: backend/vbd/3/2049 state: 1
Hey folks,
it took me two hole days to come so far: xen kernel starting, xen tools are
working etc..
So now I want to create a new domu guest. I created it with xen-create-image
--hostname=alfredo --size=8Gb --dist=lenny --memory=512M --ide --dhcp.
But when I am trying to start my new mashine I get the following error:
xm create alfredo.cfg -c
Using config file "/etc/xen/alfredo.cfg".
Error: Device 2049 (vbd) could not be connected. Path closed or removed
during hotplug add: backend/vbd/3/2049 state: 1
Okay. Googled for two hours tried everything like max_loop=64 etc but
nothing helped.
One thing I find suspicious is teh following log entry:
kernel-provided name ''evtchn'' and NAME=
''xen/evtchn'' disagree, please use
SYMLINK+= or change the kernel to provide the ...
What does it mean and how can I fix it if necessary?
So here are my releveant logs:
