Hi,
I'm running KVM on Ubuntu 14.04 server. I run a single VM with a single
vcpu on the host and compile mysql source, it takes about 13 minutes.
When I run 2 VMs compiling mysql source at the same time, configured with
one single vcpu, it takes about 17 minutes.
Is it possible takes a less comp

I'll do some investigations into the per vm memory overhead and
play with bumping the max vcpu

I am wondering if anyone has investigated how well kvm scales when supporting
many guests, or many vcpus or both.
I'll do some investigations into the per vm memory overhead and play with
bumping the max vcpu limit way beyond 16, but hopefully someone can comment on
issues such as locking probl
