similar to: guest daemon reading kvmclock - is it not needed or bad idea ?

Apologies as this is is not a specific libvirt question. Is qemu-img convert compatible with thin-provisioned LVs as targets ? I wanted to convert a file-based image to a LV image where the file-based image has a capacity much larger than the actual data it contains, so it has a small footprint on disk (either a qcow2 or a raw, but sparse, image). If I use qemu-img convert -O raw ... with a

Hi I have defined a logical pool and a volume within it # virsh vol-create-as images_lvm myvol 2G Vol myvol created # virsh vol-list images_lvm Name Path ----------------------------------------- myvol /dev/libvirt_images_vg/myvol if I try to create another volume using the previous one as backing-vol, the creation fails with what looks like an incorrect

Hi I'd want to pin the vcpu of a guest to a pcpu. the docs clearly say https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/ch09s04.html "Locking a guest to a particular NUMA node offers no benefit if that node does not have sufficient free memory for that guest. libvirt stores information on the free memory available on

Is it possible to use virsh to set the cpuset attribute of the CPU Allocation element in a domain ? <domain> ... <vcpu placement='static' cpuset="1-4,^3,6" current="1">2</vcpu> ... </domain> I have seen that virsh vcpupin and virsh emulatorpin can be used to query and set the cpusets of the <vcpupin> and <emulatorpin>

Hi, I have found the cpu time partitioning based on cpu shares weights not very intuitive. On RHEL64, I deployed two qemu/kvm VMs VM1 with 1 vcpu and 512 cpu shares VM2 with 2 vcpus and 1024 cpu shares I pinned their vcpus to specific host pcpus: VM1 vcpu 0 to host pcpu1 VM2 vcpu 0 to host pcpu1, VM2 vcpu 1 to host pcpu2 I executed inside the VMs a simple process that consume all

Hi I have a test environment where a single LVM volume group is used both as a storage pool for virtual machines' disks AND for the LVs used for the HOST system filesystem. I never use libvirt commands to start/stop/activate the pool. Only to create/delete volumes. The test environment works fine. How suitable would be a shared VG for a production environment ? thanks, Edoardo Comar

Passing '-cpu host' is meant to cause qemu to pass the same CPUID flags from the host up to the appliance. The major benefit of this is that the appliance can use all CPU features available to optimize eg. checksumming, crypto, RAID XOR operations, zero fill. However in practice this can cause strange problems on some hardware: https://bugzilla.redhat.com/show_bug.cgi?id=870071 This

Hello All, Can anyone help me solve this problem. Am trying to extract hash-tagged words from tweets downloaded from twitteR. I can extract hash-tagged words from single tweet using (stringr) str_extract_all(tweets, "#[a-z//A-Z//0-9]+")  but cannot with more than one tweet at a time except I manually remove all regular expressions and tweets numbers such as [[1]] and [1.] I want to

It makes no sense for the clock initialization to be hanging around in setup_32.c when we have a generic kvm guest initialization function available. So, we move kvmclock_init() inside such a function, leading to a cleaner code.

Avi, Hope this series is okay now. Thanks for the testing

Hola a todos, Me gustaria pedir vuestra ayuda a encontrar el error que no consigo encontrar en este archivo. He revisado todo mil veces y probado y no doy con ello.Adjunto el archivo con Google drive porque es muy grande. ? monicap_50.csv <https://docs.google.com/file/d/0B8o2KrPEgG7ATlBMc19lTVk1d3M/edit?usp=drive_web> ? Este es el script, y lo que no entiendo que pasa es que tengo 592044

since the pv_apic_ops are only present if CONFIG_X86_LOCAL_APIC is compiled in, kvmclock failed to build without this option.
