I am interested in installing smp windows 2003 server guest and have some
questions.
1. Is windows smp guest working and performing well at this point in kvm?
2. If question 1 above is true, then what HAL should I choose during
installation and what other flags should I use when running it?
Thanks for any help in advance.
Haydn

It's working will with -no-kvm-irqchip. Not so sure without the switch,
but we're improving things.
I haven't tested performance very thoroughly. What's your workload?

Good question. What HALs are available for Windows 2003 SMP?

One other question. I'm doing this a core 2 duo and am wondering about
number vcpu. I know xen for example can have more vcpus than physical cpus,
example 4 vcpus on 2 physical cpus/cores. What is the recommendation for
best performance? I would imagine a one to one ie. 2 vcpus on 2 cores/cpus?

Well, no idea what that is.

mps multiprocessor may give the best performance, though I've never
tested it.

Yes, 1:1 (or less) is best. Overcommitting cpus will definitely degrade
performance drastically.

Didn't think you would as this is more on the networking side. You may find
it interesting as it actually an emulator emulating mips architecture (
which cisco ios runs on ) on x86. You can check it out at
http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator if you care to.

First attempt at this and qemu process hung during install.. it went to
sleep and never woke up. Any suggestions on what to try next? My parameters
for install were as follows:

I'll just have to debug this. Looks like no one tried it before.

I'm using ACPI multiprocessor HAL, don't know how MPS multiprocessor HAL works.

I'm going to try the acpi multiprocessor HAL and see how that works. What
kind of performance do you get with it?

I have a question on guest smp performance. If I have a host with core 2
duo, should a kvm guest perform better using -smp 2 as opposed to not using
-smp 2?

Well, it depends:
In general Avi measured 40% performance increase for using a second cpu
in the guest. This was long time ago,
before the in-kernel-apic implementation. It might improve the gain of
the additional cpu.
On the other hand, for 32 bit windows, using ACPI HAL has pretty big
overhead at the moment. Since it is a must
for smp guest, it might be slower than running non-acpi single cpu VM.
My guess is that you better use -smp 2.

can you tell me what does the HAL means here? and what's kind of HAL
exists what are the advantage/disadvantages them. how can i
change/configure this?

but if it's part of the windows, how can a user of kvm can change or use
different version? or windows itself has more hal inside and if we run
single cpu versus smp kvm for windows the use different hal? and what
other hel can be indirectly selected by this way?

It is possible that 64 bit SMP windows have much less overhead than 32
bit, e.g if the processors are later than Core 2

Hi Avi,
Thanks for release 44. With release 44 I was able to do the following.
1. install windows 2003 enterprise server and selected ACPI Multiprocessor
HAL. However I didn't use -smp 2 during install but i don't think this
matters, does it? The parameters used during install were
/usr/local/kvm/bin/qemu-system-x86_64 \
-hda server2k3r2smp.img \
-m 512 \
-no-rtc \
-localtime \
-net nic,model=rtl8139 \
-net user \
-boot d \
-cdrom /home/hsolomon/isos/en_win_srv_2003_r2_enterprise_cd1.iso &
2. After successful install I then booted machine using -smp 2 ( Host is an
intel core 2 duo ). What I noticed is high cpu usage. Attached is a
screenshot showing host system monitor as well as virtual machine system
monitor. There's a process called "SYSTEM" in windows that hogging cpu.
Sometimes the machines dies since installing usb tablet so not sure if this
has anything to do with it.
Attached is screenshot showing load. Is there anything I can do to reduce?
Thanks.
Haydn
