[libvirt-users] Xen PVH Support in libvirt
by Tizian Lamatsch 13 Mar '18

13 Mar '18

Hello @ all, i wonder if there is any support for Xen PVH (https://wiki.xen.org/wiki/Xen_Project_Software_Overview) within libvirt. If i parse a xen native domU config file with 'virsh domxml-from-native' in which i set type='pvh' it changes it in the libvirt xml output to normal pv. Also the docs of libvirt do not state something like pvh. I am currently running Xen 4.10.0 with LibVirt 4.0.0. If it is not possible at the moment, can you please tell if this is a planned feature of libvirt? Thanks in advance for your help! Best Regards, Tizian

[libvirt-users] KVM or Qemu
by Jamie Fargen 12 Mar '18

12 Mar '18

List- I know this may be slightly off topic and if so tell me to hit up the emu-discuss mailing list, but does anyone know how to detect the difference between a guest that is being fully emulates using qemu and a guest that is running para-virtualized using KVM? I have and when I inspect the CPUs I see the following.... # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : QEMU Virtual CPU version 1.5.3 stepping : 3 microcode : 0x1 cpu MHz : 1995.312 cache size : 4096 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 4 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm rep_good nopl pni cx16 hypervisor lahf_lm abm bogomips : 3990.62 clflush size : 64 cache_alignment : 64 address sizes : 46 bits physical, 48 bits virtual power management: # dmidecode # dmidecode 2.12-dmifs SMBIOS 2.4 present. 10 structures occupying 326 bytes.

[libvirt-users] snapshot with libvirt tools or with lvm tools ?
by Lentes, Bernd 09 Mar '18

09 Mar '18

Hi, i asked already a time ago about snapshots. I have some guests, each resides in a raw file, placed on an ext3 fs which is on top of a logical volume, for each guest a dedicated lv. The raw is not a "must have", if there are obvious reasons i can convert them to a qcow2. What i want is a consistent backup of each guest taken overnight. If possible i won't have downtime. I can use the libvirt tools, but the lvm way seems to be more elegant. Before copying the file the guests resides in i take a snapshot from the respective lv. Then i mount the snapshot and transfer it via rsync on a CIFS share. Rsync seems to be the appropriate tool because i just transfer the changes in the file compared to the file from a day before. So i don't have to transfer complete and big raw files but just the difference. The guest still can be running, and after the transfer of the snapshot file i just delete it, and the next night the same procedure. What do you think ?

[libvirt-users] About .img file while creating vm
by amey pandit 09 Mar '18

09 Mar '18

Hi, I am trying to create vm using virsh create x.xml. But I am confused as what is the .img file that is required. Here is the Disk tag from my xml. <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> * <source file='/xxx/xx_vm.img'/> * <target dev='hda'/> </disk> Is it .ova file that is converted to .img ? If anybody have links or some guide related to the topic that would be really helpful. Thank you, Amey

[libvirt-users] Lib virt v4.x packages for Xenial
by Stephen Bates 06 Mar '18

06 Mar '18

Hi Libvirt Users! Apologies in advance as I am sure this has been asked before (but I could not find it in the archives). Has anyone had any success creating .deb packages for Xenial for libvirt and libvirt-bin for v4.0 or v4.1? A quick scan of the PPA respository does not show anything this recent. Is there a fundamental issue that prevents these package files being created? If so has anyone got a primer for how best to install a recent version of libvirt and associated tools on Xenial? We have a bare-metal server we have to keep on LTS but I need to be able to run recent versions of QEMU to get access to certain NVMe model features that were only recently added... Cheers Stephen
