Hi;
I wanted to see if I could get KVM nested virtualization running in a 64-Bit CentOS 6.2 Guest (under a Windows 7 64-Bit Host running Workstation 8.0.2).
This doesn't seem to be working, and I was wondering if anyone has gotten this to work (presuming it's supposed to be able to work in the first place). I'm a beginner to CentOS and KVM/QEMU, so I'm not sure how to debug the problem.
If I launch the 'Virtual Machine Manager' (in the Centos Guest), and try to create a VM, it says there are no connections. If I try to get it to 'connect', I get the status of 'connecting' forever. (See the attachment image). So, my guess is something is wrong at the 'QEMU-KVM' level.
I enabled the Vt-X/EPT option in the CentOS 6.2 Guests settings, and when I boot the CentOS 6.2 Guest, I see the 'vmx' option listed in the CPU flags, which I believe is supposed to be a good thing:
[/home/greg] cat /proc/cpuinfo | grep "vmx"
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse
sse2 ss ht syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology tsc_reliable nonstop_tsc
aperfmperf unfair_spinlock pni pclmulqdq vmx ssse3 cx16 sse4_1 sse4_2 popcnt aes hypervisor
lahf_lm ida arat epb dts tpr_shadow vnmi ept vpid
I also see that some kvm modules appear to be loaded:
[/home/greg] lsmod | grep "kvm"
kvm_intel 50412 0
kvm 305113 1 kvm_intel
And, the libvirtd Daemon appears to be running (at least according to the 'Service Configuration' panel.
Is KVM Nested Virtualization (in a Workstation 8 Guest environment) supposed to work?
If so, any ideas how I can narrow down what my problem is? Since I'm not very familiar with KVM or qemu, I'm not sure where to start.
Trying to google info. has just left me confused, since some hits mention commands like 'qemu', or a 'qemu-kvm', or a 'qemu-system-x86_64'.
I see that /usr/bin/ on my Guest system only contains two qemu commands:
[/home/greg] ls -l /usr/bin/qemu*
-rwxr-xr-x. 1 root root 317216 Jan 23 16:26 /usr/bin/qemu-img
-rwxr-xr-x. 1 root root 329504 Jan 23 16:26 /usr/bin/qemu-io
Any help would be appreciated.
Thanks;
