Hi all,
*Problem:* Nested VM images fail/freeze during booting.
*Details:*
*Hardware:*
* Model: Dell R620
* CPU: 2 x 6 x 2 (ht) Intel E5-2667
o flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe

tsc_deadline_timer aes xsave avx lahf_lm ida arat xsaveopt pln
pts dtherm tpr_shadow vnmi flexpriority ept vpid
* Memory: 192GB
* Disk: 7.0T local filesystem
*Physical Hypervisor Configuration:*
* /etc/modprobe.d/kvm-nested.conf (see below)
* /etc/libvirt/qemu/virtual-hypervisor.xml (see below)
o Runs without any problems
o Includes: <cpu ...><feature policy='require' name='vmx'/></cpu>
*Virtual Hypervisor Configuration:*
* virt-manager opens without any problems
* The virtual guest within the virtual hypervisor VM fails to boot
o I see the screen in which the boot choices are shown. After the
selection is made (either by waiting for the selection timeout,
or by explicit selection), the next screen shows a screen dump
(see below)
* /etc/libvirt/qemu/virtual-guest.xml (see below)
o Uses virbr0
o There is no /var/log/libvirt/qemu logfile as the boot up doesn't
get far enough.
I tried placing the virtual-guest.xml and image on the physical
hypervisor and it does boot up without any problems.
I've scoured the web and can't figure out why boot up is failing for the
nested VM. Can anyone think of a solution or help out in any way?
Thanks,
