Phillip, Since you didn't specified hypervisor I presume you kept in mind - KVM isn't it ? I have had FreeBSD 10.1 guests running there for a short while, but was not satisfied with performance. GENERIC kernel contains support for differen hypervisor types, but it seems this support is not equal. At XenServer I got much better numbers running guests in PVHVM mode. There is also non-official patches for kernel to allow unmapped IO that makes it even faster. So, I would say, It all depends where are you running your guest VM. KVM, XenServer, VmWare, Hyper-V -- it all be different. Cloudstack, as Ahmad said, has nothing to do with it.

I always prefer Other/Misc profiles in Xenserver, gives me a more "proper" OS, even when using linux. BTW most linux distros will enable paravirt drivers to access disk and network. Even Amazon recommends HVM: "for the best performance, we recommend that you use current generation instance types and HVM AMIs when you launch new instances.". http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/virtualization_types.html HTH Lucian -- Sent from the Delta quadrant using Borg technology!
