Hello Xlord, The CPU does have VT support and I already have the nested KVM enabled. Checking the Linux Kernel release notes I saw that the nested kvm feature was implemented in 3.10 but he EPT support is in 3.12. So Centos 7's kernel which is 3.10 does have the EPT support? Is there a way to check that...

Dear Laurentiu, Could you please check if your CPU supported from /proc/cpuinfo and lscpu ?

Hi Xlord, Yes, the CPU has support for EPT. I wrongly thought that the nested EPT was first introduced in 3.12. Following your instructions I see that I have it enabled on my system as well. However, checking the kernel commits from 3.12 on search string 'nested ept' I found about 10 code chan...

Hi, Just to let you know that we decided to send all the git notifications to the centos-docs list for the centos.org website. The git repository is hosted on https://git.centos.org/summary/?r=websites/centos.org.git (will be open soon) It's low-traffic, so centos-docs list will not receive a huge amount of notifications, but at least some people on the list will get notification when a git

...rted it, you can check from kernel parameter or options if they are disabled on purpose. You can do that via the "make menuconfig" via "https://wiki.centos.org/HowTos/I_need_the_Kernel_Source" or "https://wiki.centos.org/HowTos/BuildingKernelModules". Hope that helps!

Hello, I am looking for a Linux kernel for Centos 7 that implements a feature introduced in kernel version 3.12: "nested EPT support to KVM's nested VMX." If anyone has used this feature with Centos 7, please let me know. Laurentiu -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hum..if the live migration is not happening on a shared storage, then I think it is best to have offline migration copy to image and hook up to the destinated server instead, this is a short-cut path I suppose.

Valentin, Please check if the VM guest has vm-tools installed else the ?virsh migrate --live? parameter requirement is not fulfilled else you has to turn off the VM guest and do the offline ?virsh migrate? without ?--live? options.

Hi all, Maybe it is a stupid question, but I a totally lost.

If I try to change guest.xml using "virsh edit", I can do it, but guest doesn't starts ... Is it not possible to run i386 guests under CentOS7 amd64 kvm

Hi all, To do some tests, I have installed a new CentOS7 host (fully patched) using qemu-kvm-ev-2.3.0-31.el7.16.1 instead of qemu-kvm's default package. And I have problems with network inside my guests. All guests can ping to CentOS host but nothing more: can't resolv dns names, can access via tcp to other hosts, etc ... Using same config on other CentOS7 host, but using default
