 There can be no subnet with /32 bit mask, it's single host only.


 Actually, it is possible:

 ip addr add xxx.yyy.zzz.215/32 dev eth0
 ip route add xxx.yyy.zzz.193 dev eth0
 ip route add default via xxx.yyy.zzz.193

Of course you can do that, but it wouldn't a *subnet*. Net like network, 
system consisting of several units.
I rest my case.

Well, it is a subnet, it has just only got one host in it. I wrote it
because the question is about routing, so it's quite relevant that the
IP-addresses are not on the same subnet.

No one with any clues on what to test / look into? :-/

[CentOS-virt] 4 CPU with WinXP on Centos 5.5 KVM?

2010-05-27 Thread Marcelino Mata
Has anyone had any success getting WinXP 32bit to use 4 CPU's under
Centos 5.5 KVM?
 
I have tried everything and the best I can get is 2 CPU's.  I tried
everything listed here
http://www.linux-kvm.com/content/running-windows-smp-guests  I am using
the VIRTIO drivers.
 
Is this known limitation of KVM-83-164 (Centos5 release) with WinXP
32bit?  I think there are reports of it working with 32bit Windows 2003
(or was it Windows 2008?).
 
I know KVM is granting the 4 CPU's since Linux VM can use 4 CPU's on the
same computer.
 
Thanks,
 
Marcelino

Marcelino,

TTBOMK winxp is only going to support 2 physical cpus unless you have a
special winxp license that we have not experienced

we have never seen more than a 1 or 2 physical cpu version of winxp

eh ?

I think he means cores. And XP will see and use 4 cores.
