Re: [libvirt] How many domains can be created and run in parallel in a Host.

Or, to be more precise, libvirt should not place any arbitrary restrictions; if you encounter such a restriction, please report it as a bug. For an example of a non-arbitrary restriction, libvirt 0.8.1 can only support 64k-5900 simultaneous VNC connections to VMs (because there are only that many TCP/UDP ports). Contrast this with libvirt 0.7.7, where the limit was hard-coded to 100 simultaneous VNC connections - that is, we fixed the bug by removing the hard-coded limit. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
