Hi,
i have the following problem:
I got a amd opteron server with 32 (4*8) cpus.
Since kvm is only able to created a virtual machine with 16 cpus, i
changed KVM_MAX_VCPUS, MAX_VCPUS and MAX_CPUS
as suggested in
http://www.linux-kvm.org/wiki/images/b/be/KvmForum2008$kdf2008_6.pdf
after compiling everything is shows the right number of maximum cpus in
the virt-manager,
but it is still not working.
If i start for example my virtual machine with
kvm -m 4000 -smp 30 disk0.img
i get a segmentation fault.
in the logfile it looks like that:
[ 4440.424512] __ratelimit: 18 callbacks suppressed
[ 4440.424523] kvm[7054]: segfault at 1ae5cf6b0 ip 00000000004092ba sp
00007fff3dbb8dc0 error 4 in kvm[400000+1e1000]
Any idee what is missing or what is wrong?
cheers
cornelius
