[libvirt-users] CPU model and missing AES-NI extension
by Dennis Jacobfeuerborn 06 Feb '15

Hi, today I tried to configure a guest using Virt-Manager and used the "copy host cpu configuration" option which resultet in a "Sandy Bridge" model. What I noticed is that for example the "aes" extension is not available in the guest even though it is available on the host cpu. This is what the host cpu looks like: model name : Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz 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 syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid And this is what I get in the guest: model name : Intel Xeon E312xx (Sandy Bridge) flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb lm constant_tsc pni ssse3 cx16 sse4_1 sse4_2 popcnt lahf_lm abm Is there a way to get closer to the hardware and get as many of the host features in the guest as possible? I never intend to do anything like live-migration with this guest so compatibility for that case is not a concern. Regards, Dennis

id like to access libvirt kvm consoles from my macbook. i tried realvnc, which just crashes immediately, and the built in "screen sharing" client, which insists on a password, which i havent set. does anyone here do this? which vnc client do you use?

[libvirt-users] Vepa use vf?

1. Does vepa mode in libvirt use sr-iov ? 2. How can I do port mirroring with sr-iov? vepa This network uses a macvtap "direct" connection in "vepa" mode to connect each guest to the network (this requires that the physical interfaces used be connected to a vepa-capable hardware switch. The physical interface to be used will be picked from among those listed in <interface>subelements of the <forward> element; multiple guest interfaces can share each physical interface (libvirt will attempt to balance usage between all available interfaces).Since 0.9.4
