similar to: Support statement on Nested virtualization

Hi, I have some questions about the CPU-Capabilities for Virtualization especially for Nested Virtualization like the Turtles Project. I am trying to create a Nested Environment by following the instruction of: http://kashyapc.wordpress.com/2012/01/18/nested-virtualization-with-kvm-and-amd/ The bare-metal system is a Dell Server with following CPU-Flags (virsh capabilities) <cpu>

Hi David, thanks for the added input! I'm taking the liberty to snip a few paragraphs to trim this email down a bit.

I am using nested virtualization on a Google Cloud Compute instance. Things are generally working fine with libvirt using qemu+kvm, however I observed that <cpu mode='host-model'> is not exposing avx and avx2 instruction set to the guest Linux instance. Google Cloud platform claims the CPU model of the host compute instance is Broadwell, however libvirt capabilities maps it to

Hi all, I got a new laptop recently and what worked before no longer works (Fedora 23 on the laptops in both cases)... I'm trying to get nested virtualization to work because I use the VMs on the laptop to simulate an HA cluster that itself hosts VMs. I don't care much at all about the performance of the nested VM, it's just there so that I can work on the cluster's code.

Hi everyone, I hope this is the correct list to discuss this issue; please feel free to redirect me otherwise. I have a nested virtualization setup that looks as follows: - Host: Ubuntu 16.04, kernel 4.4.0 (an OpenStack Nova compute node) - L0 guest: openSUSE Leap 42.3, kernel 4.4.104-39-default - Nested guest: SLES 12, kernel 3.12.28-4-default The nested guest is configured with

thanks your mail，now below： If the KVM supports nested VMX and QEMU starts with the arguments -enable-kvm and -cpu ..., + vmx, then the LOCK bit of the guest MSR_IA32_FEATURE_CONTROL and Enable VMX out of SMX operation bit will be set. Well, I should add -enable-kvm parameters of the document which xml position, Exactly speaking, how to amend xml configuration file?

I am wanting to play with the amd-v virtualization processor and centos. I was just looking at an AMD6000+ CPU but did not find any mention of it have the AMD-V instructions. What AMD processors support AMD-V instructions? Jerry -------------- next part -------------- An HTML attachment was scrubbed... URL:

NB, in future please don't CC all possible mailing lists at once. Just pick the most appropriate mailing list for your question. I've dropped libvirt-list & libvirt-announce from the CC, since this is a question most suited for libvirt-users.

Hi, some custom CPU models are reported from virConnectGetDomainCapabilities as usable='yes' on a physical machine while as usable='no' inside a VM running on the same machine. That's not completely surprising. But what surprises me is that those models are still reported from virConnectCompareCPU as supported (VIR_CPU_COMPARE_SUPERSET) in the nested environment and VMs can
