It is supported in different linux flavours, but I don't like to go on that way. I read on the omniti website that kvm is one of the key-features, so nesting was something which I'd expected to be there. Don't get me wrong, the not nested kvm is working perfectly (and fast!). Is there an estimated timeline in which it should be supported or a place to launch enhancement requests? <div style="color: rgb(0, 0, 0);"> <hr tabindex="-1" style="display:inline-block; width:98%"> <div id="divRplyFwdMsg" dir="ltr">From: Michael Rasmussen <mir@miras.org> Sent: Wednesday, August 10, 2016 2:48 PM To: pieter van puymbroeck; omnios-discuss@lists.omniti.com Subject: Re: [OmniOS-discuss] oracle vm server in kvm enabled zone <div> </div> </div> <div>Seem to remember nested kvm is not supported. <div class="gmail_quote">On August 10, 2016 3:53:11 PM GMT+02:00, pieter van puymbroeck <pietervanpuymbroeck@hotmail.com> wrote: <blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex; border-left:1px solid rgb(204,204,204); padding-left:1ex"> <div id="divtagdefaultwrapper" style="font-size:12pt; color:#000000; background-color:#FFFFFF; font-family:Calibri,Arial,Helvetica,sans-serif"> Hello, Currently I'm building a new homelab based on omnios (omnios-r151018) There a kvm enabled zone is created and inside the zone I have 3 kvm-guests running. These guests are running oracle vm (xen based). All is running fine except if I want to start a linux-testvm inside oracle vm, the system complains about: Error: HVM guest support is unavailable: is VT/AMD-V supported by your CPU and enabled in your BIOS? Inside the kvm enabled zone, kvm is enabled: root@ovm1:/root# ls -l /dev/kvm crw------- 1 root sys 125, 0 Aug 10 12:48 /dev/kvm root@ovm1:/root# modinfo |grep -i kvm 207 fffffffff840a000 3a030 125 1 kvm (kvm driver v0.1) root@ovm1:/root# For sure I checked the processor itself from the global zone if it is supported: # isainfo -v 64-bit amd64 applications vmx pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp cx16 sse3 sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu 32-bit i386 applications vmx pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp ahf cx16 sse3 sse2 sse fxsr mmx cmov sep cx8 tic fpu # and to me it looks I have the required flags available. inside the lvm-guest the flags are indeed not given to the guest: [root@ovm2 ~]# uname -s -r -i -p Linux 2.6.39-400.279.1.el5uek x86_64 x86_64 [root@ovm2 ~]# cat /etc/oracle-release Oracle VM Server release 5.7 [root@ovm2 ~]# grep flags /proc/cpuinfo flags : fpu de tsc msr pae mce cx8 apic sep mca cmov pat clflush mmx fxsr sse sse2 ss syscall nx lm constant_tsc up nopl pni ssse3 cx16 sse4_1 sse4_2 popcnt aes hypervisor lahf_lm [root@ovm2 ~]# it does not matter if I start the kvm guest using -cpu host \ or using -cpu qemu64,+vmx,+aes,+sse4.2,+sse4.1,+ssse3 \ # --> this one is faster despite I have an intel cpu I use the -enable-nested flag as well, but it doesn't seem to make a difference.
