hi, i am trying to find out the max vcpus supported for any domain by my hypervisor, however i am having some trouble with the below: vcpu=5 maxvcpus=libvirt.virConnect.getMaxVcpus(conn,'kqemu') if maxvcpus <= vcpu: logging.debug('checkmaxvcpus: max vcpus on hypervisor %i is less than requested vcpu of %i' % (maxvcpus, vcpu)) return 0 else: return 1

Hi, I have set maxvcpus and vcpus options in my domU configuration file, and I can see that X number of vcpu are set for the domU. I tried to activate all the vpcus by using vpcu_avail option (using decimal to represent vpcu bitmask e.g. 24=11000) but it doesn''t seem to work, and only the first vpcu is activated (i.e. has -b- state) while all other vpcu''s set for the domU are

Hey Ian and Stefano, Please see this thread: http://lists.xen.org/archives/html/xen-devel/2013-05/msg01053.html for the debug patches and some of the discussion. These three patches fix an race that has been in QEMU traditional for a long time. The guts of the bug is that if you have a guest with these options: vcpus=1 maxvcpus=32 and do ''xl vcpu-set <guest> 32'' the

Hi, I''m trying to build a xen-qemu-dm-4.0 package to support the HVM part of the Xen 4.0 package that will be soon in Debian experimental. When I start an HVM domain, I have the following subject line of this thread in my /var/log/xen/qemu-dm-XXXX.log file, and then it stops here. Any idea what I should do to fix? Thomas P.S: my build is using a clone of

Hi, I ran into a strange behavior with libvirt snapshots. I have some vms running with thin-provisioned qcow2 disk images (libvirt 1.1.3 with fedora 20). * When I create a snapshot on the VM, the qcow file suddenly grows big, somewhat bigger than the maximum size of the disk. * When I delete the snapshot, the allocated disk space is not freed up, the qcow image remains the same size. However, if

Hello, First of all, happy new year! I am interested in the hot plugging facilities of libvirt, in particular in what qemu calls 'hot add' of network interface cards. (And also the reverse: hot unplugging/removing of NICs.) I think I am overlooking something, but so far the best I have been able to find is: http://libvirt.org/sources/virshcmdref/html/ and it is not entirely clear

Hi, I have found the online command reference somewhat incomplete so I thought I give it a try and fill in some of the gaps, but when I cloned the repo I noticed that the last commit happened a little more than 3 years ago. Do you guys accept patches for the documentation? What is the plan in general for the future on the documentation front lines? -- EOF

Please see the three patches that fix the ACPI AML and QEMU race. They have been Ack-ed by both George (for inclusion in Xen 4.3) and by Stefano. They should be candidates for back-port in older hypervisors. Konrad Rzeszutek Wilk (3): piix4acpi, xen, vcpu hotplug: Split the notification from the changes. piix4acpi, xen: Clarify that the qemu_set_irq calls just do an IRQ pulse.

Hi, I have installed Debian Buster with encrypted LVM so apon installation my root partition is encrypted. So far so good but as soon as I encrypt the boot partition, after reboot the OS won't start. If I start the drive directly with qemu, it works but it looks like Libvirt is somehow not able to deel with it. What am I missing? -- John Doe

Hi Everybody: I am trying to get virt-install to work with a kickstart file that is on the local file system. I tried using the --initrd-inject="/tmp" --extra-args="ks=file:/myks.cfg" but I got this error message: ERROR --extra-args only work if specified with --location. Here is the basic command: virt-install \ --accelerate \ --cdrom

Hi All, We did some testing for Xen-unstable tree with upstream QEMU. We covered basic guest booting up, power management, VT-d, SR-IOV features. We found 4 new bugs which only exist in upstream QEMU not in qemu-xen. We followed the below wiki page to use upstream QEMU. http://wiki.xen.org/wiki/QEMU_Upstream test tree: xen-unstable-tree.hg: C/S 26193 (about 20 days ago) qemu.git: commit

Hi All, We did a round testing for Xen 4.2 RC1 (CS#25692) with Linux 3.4.7 dom0. We covered VT-d, SR-IOV, Power Management, TXT, IVB new features, HSW new features. We covered many cases for HVM guests (both Redhat Linux and MS Windows guest). We tested on Westmere-EP, SandyBridge-EP, IvyBridge desktop, and Haswell hardware platforms. We found no new issues, and verified 1 fixed bug. Fixed bug

All, These days I am trying to understand the interaction relationship between the libvirt and KVM kernel module, eg. kvm_intel.ko. We know that KVM kernel module expose an entry in form of device file "/dev/kvm" which can be accessed by user space application to control, for example, create a VM using KVM_CREATE_VM with help of ioctl. Now let's say the tool virsh based upon
