Bug Description

paravirt guests work.

followed instructions: http://www.math.dartmouth.edu/~sarunas/xen_304_hvm_etch.html (For HVM guest)

$ sudo xm create -c winxp
Using config file "/etc/xen/winxp".
Started domain winxp
xenconsole: Could not read tty from store: No such file or directory

/etc/xen/winxp:

kernel="/usr/lib/xen-ioemu-3.1/boot/hvmloader"
builder='hvm'
device_model='/usr/lib/xen/bin/qemu-dm'
memory=1024
name='winxp'
vif=[ 'type=ioemu' ]
disk=['file:/xen/images/winxp.img,ioemu:hda,w','file:/usr/local/iso/winxp.iso,hdc:cdrom,r']
boot='d'
vnc=1

according to this thread there should be log files in /var/log/qemu*
that will help to debug the problem.

Finally, why is hvmloader in: /usr/lib/xen-ioemu-3.1/boot/hvmloader?
It doesn't need to be a moving target for users... could there at least be a consistent symlink so that tutorials can be written for hvm and consistency remains?

I will attach the xend.log

UPDATE:

needed to fix device_model line too...

from above
-device_model='/usr/lib/xen/bin/qemu-dm'
+device_model='/usr/lib/xen-ioemu-3.1/bin/qemu-dm'

seems to work now... it is a big slow, and slows down the system a bit (uses a lot RAM), it is allocated 1GB of a 4GB (amd64) system

it does work though.

I think that a qemu-dm symlink should be made as well.

typo from above big --> bit

Also, to clarify, the hvm guest is not actually using any more RAM than it is supposed to. firefox is caching a lot as usually and that coupled with the fact that the install of XP is disk intensive, slows down the system...I will update after I finish the XP install and boot it up.

I finished the install, rebooted the computer and enable remote desktop on XP. I runs pretty snappy and the system doesn't show a lag anymore.

I think it is working well. This bug can be closed... I will add a feature request for the symlinks.

Todd, have you added the feature request already? I have run on exactly the same problem with xenman (now convirt) when I was trying to use it with xen3.1 in Gutsy.
The symlinks should be definitely added to the Gutsy package of xen 3.1.

Is this symptom still reproducible in 8.10 beta or later?

Hi, Daniel

Sorry.

Can anyone confirm this on Ubuntu 9.04, or even better 9.10 alpha4? Thank you

FYI : on debian, the file /var/log/xen/qemu-dm-X.log may contain more explanations on the trouble.
