Hi James;

be the problem or did you just make a typo in copying it into the email?

You are right, my bad - I was typing the command wrong - it should be
domain/0.  The output you want is:

domain = "qcow"
frontend = "/local/domain/75/device/vbd/768"
uuid = "b01d6f19-e818-f976-a284-ed9a3097d857"
dev = "hda"
state = "2"
params = "qcow:/xenimages/w2k3/w2k3.qcow"
mode = "w"
online = "1"
frontend-id = "75"
type = "tap"
hotplug-status = "connected"

I will have a look at debugview next.

Cheers

G

As you say below, 0x7B is a 'can't find boot device' error.

All your examples above say 'domain0' instead of 'domain/0'. Could that
be the problem or did you just make a typo in copying it into the email?

If that doesn't work, just do xenstore-ls /local/domain/0 and tell me
what the domain number is and I'll figure it out from there.

Another thing you could do is to boot with a file: block device, fire up
debugview, and then do a 'xm block-attach' to add the tap device at
runtime and see what debugview says.

I might have a go at using tap too to test it.

Hmmm... no evidence of unaligned buffer access. The queue only seems to
get to a maximum of 8 requests though during the tests which is a bit
strange.

Not sure... maybe we'll stick to -users for now just to be safe.
