Ciao Charles,
sorry for this silly question, but I can't compile kvm-79 for AMD 64bit
Please pardon me for following up on one silly question with another --
but is your host running a 64-bit userland? (What is the output of
uname -m?)

Hi,
I want to divide host CPU performance between 2 VM in specified ratio. I use

My scenario:

running on host CPU with 4 cores

Hi,
this patch series introduces multiple NUMA nodes support within KVM guests.
This is the second try incorporating several requests from the list:
- use the QEMU firmware configuration interface instead of CMOS-RAM
- detect presence of libnuma automatically, can be disabled with
./configure
The attached patch parses the command line options given at -numa and
passes it on to lower levels (namely qemu-kvm.c)

According to the host node map given on the command line the VCPUs are
pinned to the respective node (allowing at least scheduling between the
cores belonging to this node). The mmap'ed guest memory will be bound to
the correct host nodes (this will of course not take effect until the

According to the NUMA topology passed via the QEMU firmware
configuration interface the BIOS code generates a SRAT (System Resources
Affinity Table) to describe which (V)CPU and which part of memory is
assigned to a certain node. This will then be read and hopefully honored
by the guest OS.

Hi Andre,
This patch series needs to be posted to qemu-devel. I know qemu doesn't
do true SMP yet, but it will in the relatively near future. Either way,
some of the design points needs review from a larger audience than
present on kvm-devel.
I'm not a big fan of the libnuma dependency.
