As people may know, we frequently encounter errors caused by libvirt when running the libguestfs appliance. I wanted to find out exactly how frequently these happen and classify the errors, so I ran the 'virt-df' tool overnight 1700 times. This tool runs several parallel qemu:///session libvirt connections both creating a short-lived appliance guest. Note that I have added Cole's

Hello All, Since 4.5.0-23.el7 version (Red Hat 7.7), when I launch pinned VM, libvirtd reset CPU affinity to all enabled in host CPUs, if it runs in custom cpuset. I can't reproduce this behavior with 4.5.0-10.el7_6.12 with the same kernel version (Red Hat 7.7). Libvirt runs in a custom cpuset 'libvirt', where the number of available cpus is restricted to 0,2,4,6,8. And this

...puts -no-shutdown on your command line. Then, libvirt has a handler for various guest events - e.g. when the guest reboots (well, when it calls 'reset'). But when looking at its implementation it looks like there is something missing: http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/qemu/qemu_process.c;h=a11d75b80fb018da777fa013a1c5c0762568ac19;hb=HEAD#l478 Compare it to say SHUTDOWN event: http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/qemu/qemu_process.c;h=a11d75b80fb018da777fa013a1c5c0762568ac19;hb=HEAD#l631 Therefore I think this is a bug. Let me see if I can propose a fix for it. M...

...eading the graphics output of each virtual machine at a low level, however I cannot find the exact point where the server is. Currently I am trying to understand the function "virDomainOpenGraphics" in libvirt.c and, at a lower level, the function "qemuProcessHandleGraphics" in qemu_process.c, but I 'm not sure if it is possible to get what we need from them. I would appreciate any help or clue you could provide regarding this issue. Thank you very much in advance. Best regards, -------------- next part -------------- An HTML attachment was scrubbed...

Using virsh edit, I made the following change to the domain XML file: <on_reboot>destroy</on_reboot> But this appears to do nothing. The VM guest is Windows 10, and when directing it to reboot, it still reboots, instead of shutting off the VM. I was trying to work around some kind of a bug, somewhere, that started happening after updating to Fedora 26 and qemu 2.9, where a

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

Hi, all. I want to know when I press run button. start a domain. What is the procedure of libvirt internal. I know it will call virDomainCreate(),then qemuDomainStart() -> qemuDomainStartWithFlags(). what is the next? xuanmao_001 -------------- next part -------------- An HTML attachment was scrubbed...

Hello, In the .xml file I use a media which is no longer available. In the past, I got the information media not available and the creation of the VM was stopped - O.k. behavior. Since 3.10 the libvirtd stopped promptly and all open consoles windows and the virt-manager closed promptly. For diagnose: etcsvms1:/kvm/CS8200/M5 # coredumpctl TIME PID UID GID SIG
