Dear All, I'm reaching this mail-list to ask a small question about disabling '3dnowprefetch' CPU feature in Xen Guest using libvirt. This is my environment: Fedora release 26 (Twenty Six) 4.11.0-0.rc3.git0.2.fc26.x86_64 xen-4.8.1-2.fc26.x86_64 libvirt-3.2.1-1.fc26.x86_64 I can disable '3dnowprefetch' CPU feature in guest via 'xl' command,

The problem desribed here: https://bugzilla.redhat.com/show_bug.cgi?id=593266 Please update http://www.libvirt.org/formatdomain.html and describe NEW xml tags, like <serial>xxxx</serial> for hard drive and all cpu tags, other if any. -- Segmentation fault

In the fake <domain type='physical'> libvirt XML that we create to describe the physical host, we did not accurately pass any information about the host CPU except the number of cores (<vcpu/>). This commit extracts detailed information about the vendor, model and topology of the host CPU and adds that to the libvirt XML for virt-v2v. Conveniently we can use libvirt

After the previous commit, wherever we had: start_element ("foo") { string ("bar"); } end_element (); this can now be replaced by: single_element ("foo", "bar"); --- common/utils/libxml2-writer-macros.h | 2 +- lib/launch-libvirt.c | 78 ++++++++-------------------- p2v/physical-xml.c | 15 ++---- 3 files

Don't get the CPU information from libvirt, because including libvirt and all dependencies in the virt-p2v ISO bloats everything. Instead get most of the information we need from the util-linux program 'lscpu'. Unfortunately the CPU model cannot be retrieved. Example output: $ ./run virt-p2v --cmdline="p2v.dump_config_and_exit" [...] cpu vendor . . . Intel cpu

I've been trying to follow the information found here [1] in order to provide an alias for RBD disks I'm defining, however it does not appear to be working and I wanted to see if I was doing something wrong. I define the alias like so (using 'virsh edit'): <disk type='file' device='disk'> <driver name='qemu' type='qcow2'

Hello All: I am trying to set the hostname of VMs at boot time and banging my head against the wall. I am using virsh create xen-config.xml to boot a Scientific Linux 5.5 image. I have gone through the libvirt domain xml format at http://libvirt.org/formatdomain.html#elementsResources and I don''t see anywhere to set the hostname in there. I am using pygrub for the bootloader

Hi, I?m testing to start a KVM-VM with different CPU settings and I get an weird error when I use the parameter: <cpu mode='host-model'> !! I have a AMD Opteron 4280 CPU, but in the VM, proc/cpuinfo shows me, that I?m using Intel core2duo cpu model T7700 and in the flag-line of proc/cpu the system is listing the svm-flag of AMD?!?! If I use <cpu

I've got a problem where I can't access my console (well, I can', but I can't type in a password), which I don't think is a libvirt issue but any help or commentary is certainly welcome http://thread.gmane.org/gmane.comp.emulators.kvm.devel/79561 , and I'm trying to debug it by trying out different console/serial options in my .xml file, and I can't change them.

I have a system where I spawn a single libvirt daemon process in the default network namespace. Once the daemon is running, I create and start VMs using the virDomainDefineXML API (defines a VM or "domain" but does not boot it) followed by the virDomainCreate API (boot the VM). Now, I am trying to create these VMs in generic network namespaces provided by the user e.g.,

Hi, I'm looking at adding support to vagrant-libvirt to add some additional XML to the network definitions it creates following https://libvirt.org/formatnetwork.html#general-metadata assuming the metadata element is to be treated the same as what is listed for domains https://libvirt.org/formatdomain.html#general-metadata (app metadata isn't explained What I was wondering is if there

Hello all, I am attempting to use the 'virsh attach-device' command to add storage to a guest from a pre-defined iSCSI-based storage pool. My desire is to attach a volume from the storage pool and have the storage pool recognize that the volume is in use and either flag it as such, or remove it from the pool so that subsequent queries to the pool will only return available storage

you can set the CPU type and model and features https://libvirt.org/formatdomain.html I usually give it during the virt-install as -cpu core2duo,+vmx (the ,+vmx will enable vmx vt extensions on the guest CPU ) ... <cpu match='exact'> <model fallback='allow'>core2duo</model> <vendor>Intel</vendor> <topology sockets='1'
