------- Comment From [email protected] 2025-03-28 15:45 EDT------- Hi I'm seeing success in defining a virtio-mem-ccw device via `virsh edit`. However I'm seeing failure when I try hotplugging a device.
``` # virsh edit u25 ... # virsh start u25 ... # virsh dumpxml u2410 | grep virtio-mem -A10 <memory model='virtio-mem'> <target> <size unit='KiB'>9437184</size> <block unit='KiB'>2048</block> <requested unit='KiB'>0</requested> <current unit='KiB'>0</current> <address base='0x80000000'/> </target> <alias name='virtiomem0'/> <address type='ccw' cssid='0xfe' ssid='0x0' devno='0x0006'/> </memory> # cat ./virtio-mem.xml <memory model='virtio-mem'> <target> <size unit='GiB'>9</size> <block unit='MiB'>2</block> <requested unit='KiB'>0</requested> </target> <address type='ccw'/> </memory> # virsh attach-device u25 $PWD/virtio-mem.xml error: Failed to attach device from /var/lib/libvirt/images/virtio-mem.xml error: internal error: unable to execute QEMU command 'device_add': PCI-attached virtio based memory devices not supported ``` Hotunplug succeeds however. ``` # virsh dumpxml u2410 | grep virtio-mem -A10 > ./live-definition.xml # virsh detach-device u2410 $PWD/live-definition.xml Device detached successfully ``` Additionally virtio-mem-pci does not work at all, logging the same error message as above: `PCI-attached virtio based memory devices not supported`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2097886 Title: [25.04 FEAT] [VS2027] KVM: Enable virtio-mem support - libvirt part To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/2097886/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
