xen discuss - Jun 2009 - viridian not working in curretn xvm-gate 3.4??

I have got my win2k8 vm running with the attached config file (fresh 
install). But there are no hyper-V or so stuff, just the normal qemu 
nerv which produces single thread cpu load in dom0 => not really fast.
So has someone tried it with success?
Or do I have to change some thing?

so the problem you had earlier was with the maxmem and memory
setting?

BTW, are you using a FC disk or iSCSI?




Thanks,

It is mentioned that win2008 will have some services like Hyper-V 
shutdown... running if it detects it runs on hyper-v, additionally the 
qemu emulated devices are still used, I would think this is the most 
important part of having guestOS support, that the software emulated 
devices are not needed (they are really slow).

Or let it turn around how could I determine that my win2k8 has detected 
that viridian is available?
And what should be the benefit?
Howto get the enlightenment stuff running and what will it give me 
currently? para-virtual io?

regards,
Florian

You should see some info on the Xen console (see ''xm dmesg'').
There
might be a way to check it in win2k8 itself too, but I wouldn''t know 
offhand.

Right now, the hyper-v enlightenments as implemented by Xen don''t 
provide you with all that much, although they are useful items. There 
are three items: 1) APIC access through MSRs (could be a win for 32bit 
Windows), 2) Windows will give up the VCPU when it spins too long on a 
lock (useful for busy systems where VCPUs are fighting for physical 
CPUs), 3) Windows will relax its timer checks (avoids the dreaded bug 
check 0x101 BSOD).

I don''t know if you noticed, but starting with the 3.3 bits we
have iscsi support (with migration).
   phy:iscsi:alias/<iscsi-alias>
   phy:iscsi:static/<server IP>/<lun>/<target id>
   phy:iscsi:discover/<lun>/<alias or target id>

e.g.
     disk = [''phy:iscsi:alias/serv01-iscsi/winxp05-disk0,0,w'']
     disk =
[''phy:iscsi:static/192.168.0.70/0/iqn.1986-03.com.sun:02:17f34578-00a9-ef69-f3e9-b8a2896a4915,0,w'']

I also put in the infrastructure for FC too.. There just needs
to be an additional script file..

i.e., you would do something like...
   phy:san:/<lun>/<guid>/

and create a script file "/usr/lib/xen/scripts/vbd-san" which looked
similar to /usr/lib/xen/scripts/vbd-iscsi. i.e. the backend will
look for dynamic-device-path before looking at params.

Then you wouldn''t have to worry about controller numbers etc
during migration.

Will it shutdown the machine cleanly using an xm shutdown?
