I thought you were running Scientific Linux 6 as a host too which also has vendor specific packages, but at least something that I can easily look into :) Can you reproduce with upstream kernel/qemu? If it works on upstream you can open bug in Ubuntu. > One of the things that we did, we try to update libvirt to the > last versions > because we are using for our cloud the version of ubuntu 10.04 and the > last stable version of libvirt was 0.7.5-5ubuntu27.23, but when > we try to > get the capabilities, we get the following: This is definitely not libvirt fault. This is either kernel or qemu. Looking into git history 3dnow/3dnowext support was introduce into the kernel kvm component before 2.6.32 though. > > root@vfalbor-desktop:~/# virsh capabilities | grep 3dnow > <feature name='*3dnowprefetch*'/> > root@vfalbor-desktop:~/# > > but in the cpu_map.xml file we find the 3dnow and 3dnowext for > our architecture: > > root@vfalbor-desktop:~/# cat /usr/share/libvirt/cpu_map.xml | > grep 3dnow > <feature name='*3dnowext*'> <!-- CPUID_EXT2_3DNOWEXT --> > <feature name='3dnow'> <!-- CPUID_EXT2_3DNOW --> > <feature name='3dnowprefetch'> <!-- > CPUID_EXT3_3DNOWPREFETCH --> > > Thanks Gleb, > Víctor Fdez. > > El 09/07/13 17:16, Gleb Natapov escribió: > >On Tue, Jul 09, 2013 at 05:07:57PM +0200, Victor fernandez wrote: > >>Yep, > >> > >> -> this is for the host: > >> > >> root@vfalbor-desktop:~# cat /proc/cpuinfo | grep flags | uniq > >> flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr > >>pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx > >>mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc > >>rep_good nonstop_tsc extd_apicid amd_dcm pni monitor cx16 popcnt > >>lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse > >>3dnowprefetch osvw ibs skinit wdt nodeid_msr > >> > >> -> this is for the VM: > >> [root@sl6 ~]# cat /proc/cpuinfo | grep flags | uniq > >> flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr > >>pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext > >>fxsr_opt pdpe1gb lm rep_good extd_apicid pni cx16 popcnt lahf_lm > >>cmp_legacy cr8_legacy abm sse4a misalignsse 3dnowprefetch > >> > >Hmm, what is your kernel and qemu versions? > > > >>El 09/07/13 17:00, Gleb Natapov escribió: > >>>On Tue, Jul 09, 2013 at 04:57:13PM +0200, Victor fernandez wrote: > >>>> 2.- with the "-cpu host" parameter: > >>>> > >>>>/usr/bin/kvm *-cpu host* -m 2048 -smp 1 -name i-2-11-VM -monitor > >>>>telnet:127.0.0.1:9941,server,nowait -boot c /mnt/b07f7f29-7b9b-3d4b-b170-77876d10e7b1/134bc689-1207-487c-ae95-6c0dc2e0f285 > >>>>-parallel none -usb -usbdevice tablet -vnc :0 -vga cirrus -net > >>>>nic,macaddr=06:00:90:00:00:08,vlan=0,model=e1000,name=e1000.0 -net > >>>>tap,script=/usr/bin/qemu-ifup,vlan=0,name=tap.0 > >>>> > >>>With this command line can you provide output of /proc/cpuinfo on the > >>>host and the guest? > >>> > >>>-- > >>> Gleb. > >>>-- > >>>To unsubscribe from this list: send the line "unsubscribe kvm" in > >>>the body of a message to majordomo@xxxxxxxxxxxxxxx > >>>More majordomo info at http://vger.kernel.org/majordomo-info.html > >-- > > Gleb. > -- Gleb. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
