Xen devel - Aug 2012 - Bug report about Windows 7 pro 64 bit domU on xen-unstable dom0 with qemu traditional

>Because the save / restore and cd-insert on qemu-xen for now are not

>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

>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
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.
