Hi all, I am trying to install nested Esxi 6.x under a Centos7 kvm host to use it as test lab for new ESXi versions, but I am doing something wrong because I can't install it. I have configured kvm and kvm_intel modules with the following options: options kvm ignore_msrs=1 options kvm_intel nested=1 ept=1 and I add the following options in <cpu> xml guest file: <cpu mode='custom' match='exact'> <model fallback='allow'>Westmere</model> <feature policy='require' name='vmx'/> </cpu...

Hi, I’m struggling with virsh not detecting my hugepage mount. I have the following kernel command line: BOOT_IMAGE=/vmlinuz-4.8.13-gentoo root=/dev/mapper/gensd-gentoo ro quiet splash intel_iommu=on video=efifb:off,vesafb:off,simplefb:off splash=verbose,theme:livedvd-aurora kvm.ignore_msrs=1 transparent_hugepage=never hugepages=3072 softlevel=qemuvm My startup script outputs the following: hugetlbfs /var/lib/hugetlbfs hugetlbfs rw,relatime,pagesize=2097152,uid=77,gid=77,mode=0770 0 0 [2016.12.13 22:22:50 virsh 2808] ERROR Failed to start domain win10 [2016.12.13 22:22:50 virsh 2808]...

I've been having intermittent network issues on my Host - they go away when I stop and disable libvirtd and then reboot. They do not go away if I just stop libvirtd and don't reboot. I'm at a loss as to where to start with my troubleshooting, and being a relative n00b to libvirt, I'd love any pointers. Regards, Richard
