hi list members,
i had several problems with my new xen installations, 4.2 unstable with
2.6.39-3 and hvm guests. I can finally say that almost all problems have
been gone :-) to be honest I believe the kernels 2.6.39.1/2 and 3 were the
problem.
this weekend I used the mainline 3.0.0 kernel with an actual version of xen
4.2 unstable, and here we go:
- booting of squeeze guests, ok (before hang on grub)
- booting of win 7 x64 guests, ok
- booting of win 2008r2 x64 guests, ok
the only little problem which has left is on squeeze guests.
the squeeze guest comes up until grub. but then it takes around 2 minutes
until the squeeze guest installation continues to start up. that would be
really nice get to be solved in the near future.
thanks walter

stefano,
i found the problem, if it is really a one! I will explain it step by step
what solved my problem which works for both, win7 and debian squeeze
guest's:
network card / network
**********************
the guest network works brilliant only with that configuration:
auto brX
iface brX inet static
address 10.41.10.42
netmask 255.255.255.0
network 10.41.10.0
broadcast 10.41.10.255
gateway 10.41.10.1
bridge_ports eth0
bridge_stp on
bridge_maxwait 0
vif = [ 'bridge=brX,mac=xx:xx:xx:xx:xx:xx' ]
strange is that I now have to configure a bridge interface. with older xen
version it was enough to setup "bridge=eth0". now I had to setup
"bridge=brX"!
disk controller
***************
for a windows 7 x64 guest system I got it running with:
disk = [
'phy:/dev/vgmain/lv_server01,hda,w','file:/var/xen/win7.iso,hdc:cdrom,r' ]
for a debian squeeze guest system I needed to change it into:
disk = [
'phy:/dev/vgmain/lv_server01,sda,w','file:/var/xen/debian-6.0.1a-amd64-netin
st.iso,hdc:cdrom,r' ]
even here is strange that debian squeeze guest's now see the qemu disk as a
"SDA". squeeze used to see qemu disk in older xen versions (< 4.2) as "HDA"
and that definitely doesn't work anymore.
I found that out having a deeper look at the debian installer log.
guy's, thank you very much for your help, had become a lot of new input's. I
hope I could give some useful feedback back to you too.
finally I only would like to know, if this SDA-behavior is now a new
behavior of xen 4.2 ++?
thanks a lot, walter

What exactly are the network card and disk controller that you are seeing in
your guests?
