This XML snippet of your disk device is correct. The <shareable> element should allow the disk to be shared. But as Fei noted, your libvirt is not passing 'share-rw=on' when invoking qemu. There is an upstream patch to fix it, which will be included in the upcoming libvirt 3.10.0 release. -- You are receiving this mail because: You are on the CC list for the bug.

Ok thank you, but in the last kernel update i have problem with the network too, libnetcontrol and including virtualbox can't create a bridge network, i will change to leap 42.3 and hopefully that this stable version i not find this error. if you know that leap 42.3 is working all fine, tell me pls, that will be a great help. -- You are receiving this mail because: You are on the CC list for the bug.

Leap 42.3 is certainly more stable than bleeding-edge Tumbleweed, but that's not to say you wont encounter bugs in your environment/use-case. No software the size of a libvirt+qemu stack is bug free :-). -- You are receiving this mail because: You are on the CC list for the bug.

ok, but actually in the net there is a crisis on the virtualization side with the new kernel, and last updates of the tools, i am looking is if on 42.3 is working virtualization without this problems, because i am on a clean install of TW, and the only package installed are the kvm patterns -- You are receiving this mail because: You are on the CC list for the bug.

where i put this code "-device virtio-blk-pci,drive=vda,share-rw=on # share-rw=on" on the xml file. -- You are receiving this mail because: You are on the CC list for the bug.

"-device virtio-blk-pci,drive=vda,share-rw=on
You can't put that in the VM XML config. Fei was giving an example of how you would use the 'share-rw' option if invoking qemu directly. I suggest waiting until libvirt 3.10.0 is available early next week, where the bug you have encountered is already fixed. -- You are receiving this mail because: You are on the CC list for the bug.

ok, thank you very much, i have recently update the TW system and fix all bugs/glitch/error for run and/or install a VMs with virt-manager, and too fix network bug with kvm/qemu and virtualbox. thank you for your attendance. -- You are receiving this mail because: You are on the CC list for the bug.
