[Xen-devel] Several issues with Xen 4.1.1 regarding Windows guests (and more...)

[Georg Bege <therion@xxxxxxxxxxxx>]

Hello

Im experiencing serveral issues right now, Im not well Xen experienced -
I tried it first in '06 and staid off from it since last week.

a) Im unable to install Windows 7 guests,
I can install them perfectly but on "Setup is preparing your computer
for first use" it simply stalls.
xentop says its in blocking mode, its consuming some cpu but just 1% or
so.

b) I managed to install Windows XP fine, however the performance (I/O in
general) is quite poor compared to VirtualBox.

c) If the XM hypervisor starts it holds several seconds on its
initialization.
(After the last loading module... line from grub)

d) Problem c) occurs again if the Dom0 kernel loads.

Additionally I'll append some outputs of xm dmesg, info and dmesg.
Im running Gentoo (mostly stable stuff / 64bit).

Im gonna give you my configs I used:
----------winxp-testing.hvm--------------

arch = os.uname()[4]
if re.search('64', arch):       arch_libdir = 'lib64';
else:                           arch_libdir = 'lib';
