Bug report about Windows 7 pro 64 bit domU on xen-unstable dom0 with qemu traditional

[Fabio Fantoni]

[-- Attachment #1.1: Type: text/plain, Size: 3486 bytes --]

Because the save / restore and cd-insert on qemu-xen for now are not 
working I had to fall back onqemu-xen-traditional.
Dom0 is Wheezy 64 bit with xen 4.2.0-rc1 from source
I tested Windows 7 pro 64 bit domU with gplpv (last build 357).
xl create is working
xl shutdown is working
vnc is working, but with vfb line on configuration file is not working
save/restore is working but on restore network is up but not working
cdrom is not working, see empty device also if there is cdrom

After there are the content of domU configuration file and log, if you 
need more information tell me and I will post it.

I have seen the same problem, with cd-rom in windows 7 64 bit. When I check device manager
the CD or DVD drive is listed with the right size of the media, but the filesystem is listed as RAW.
If I exchange the real device (/dev/sr0) with an iso file, windows is able to read from the cd-drive
without problems. I am also using qemu-xen-traditional as I use PCI-passthrough. For me the
problem is there both with and without pv-drivers installed.

Thanks for reply, I have tried iso instead of phisical cdrom and it works.
I have also tried hotplug cd change but there is a bug
