Re: [libvirt] [Qemu-devel] [PATCH] vl.c: Support multiple CPU ranges on -numa option
Eduardo Habkost <ehabkost(a)redhat.com> writes:
This allows "," to be used a separator between each CPU
range. Note
that commas inside key=value command-line options have to be escaped
using ",,", so the command-line will look like:
-numa node,cpus=A,,B,,C,,D
This is really, really ugly, and an embarrassment to document. Which
you didn't ;)
What about
-numa node,cpus=A,cpus=B,cpus=C,cpus=D
Yes, QemuOpts lets you do that. Getting all the values isn't as easy as
it could be (unless you use Laszlo's opt-visitor), but that could be
improved.
Note that the following format, currently used by libvirt:
-numa nodes,cpus=A,B,C,D
will _not_ work yet, as "," is the option separator for the command-line
option parser, and it will require changing the -numa option parsing
code to handle "cpus" as a special case.
No way.
