[SOLVED] CT start works, VM doesn't start? Proxmox 4.0

[fips]

Hey,

I setup a 4.0 testing environment on an old HP DL350G5 (my productive system running on 3.2 like a charm ;-)

Installing a LXC container was not a big issue, it worked as expected.
But after installing a KVM VM, it doesn't start.
It tells me it could not load the kernel module.

kvm module is loaded, modprobe kvm_intel is not supported.
VT is enabled and I can see the vmx CPU flag in /proc/cpuinfo.

Why I can start CT but now VM's?

Thanks

Hey,

That's because those are two completely different technologies. Containers processes run as processes on the host system while with KVM/QEMU a full system gets (para-) virtualized.
CT are limited to certain linux guest and VMs can run arbitrary guests.^[1]

Short, LXC CTs do not need a Kernel module, while KVM VMs need one.

Did you enabled the Virtualization features in the BIOS? That could be needed even if the vmx flag shows up

I checked BIOS again, and of course VT was disabled

Thanks, Problem solved.
