Hi all,
SCSI passthrough of DVD drive is tried on Windows.
If vcpus=1 is used, it works.
However, if vcpus=2 is used, it does not work.
The log is as follows.
Hardware:
DELL Optiplex 990
Intel Core i5 2500
Software:
xen 4.2-unstable (25452:6bea63e6c780)
dom0: Linux 3.1.0-rc10+ 64bit
domU: Windows 7 SP1 64bit
GPLPV 0.10.0.357
domU config:
kernel = "hvmloader"
builder='hvm'
memory = 2048
name = "win7x64"
vcpus=2
vif = [ 'type=ioemu, mac=00:16:3e:19:18:7b, bridge=virbr0' ]
disk = [ 'file:/etc/xen/win7x64.img,hda,w' ]
device_model = 'qemu-dm'
sdl=0
opengl=1
vnc=1
vnclisten="0.0.0.0"
vncpasswd=''
stdvga=0
serial='pty'
tsc_mode=0
command:
# xm create /etc/xen/win7x64.hvm
# xm scsi-attach win7x64 1:0:0:0 2:0:0:0

Thanks for that. That locking code is really nasty... do you think your patch is fixing the problem or just working around it?
