Still appears to be broken in today's rawhide. The lowering of cpus works for me. Just look at /proc/cpuinfo from inside the guest domain. Raising the number of vcpus beyond what the guest booted with does not work, however. I'll take a look at the code... It seems that the vcpus parameter in the config file sets the maximum number of possible vcpus for the domain. You should be able to set the current vcpus to any number at or below this value. The hv code does not support changing the value, in any case. Code comment: /* * Can only create new VCPUs while the domain is not fully constructed * (and hence not runnable). Xen needs auditing for races before * removing this check. */ |
