guest agent stuff doesn't work due to bug 1634765. Please retest with a workaround (you can change permissions on the socket file) or once that is fixed. I tried to check the permissions of the guest agent socket file but I cant find it in the path /var/lib/libvirt/qemu/channel/target/domain-100-hotplug_76/ [root@lynx10 target]# ll -a /var/lib/libvirt/qemu/channel/target/domain-100-hotplug_76/ total 8 drwxr-x---. 2 qemu qemu 4096 Oct 3 17:25 . drwxr-xr-x. 3 qemu qemu 4096 Oct 3 17:25 .. Do I need to change the permissions of another socket file? If so, could you please provide me details about the workaround(the relevant socket file and permissions). Otherwise, I will retest it when it will be fixed. The VM needs to be running. Otherwise I provided link to fixed libvirt build in private comment #2 The VM ran while I checked it. /var/lib/libvirt/qemu/channels/, not /var/lib/libvirt/qemu/channel/... Somehow I can't reproduce the bug even if I don't change the permissions of the socket file. Nevertheless the bug can't vanish. well, if you can't reproduce it then it does end up as CLOSED WORKSFORME:) Please re-open if this can be reproduced. |
Created attachment 1489925 [details] logs Description of problem: An extension of the memory with hotplug completed fine. But memory does not expand on the VM. Version-Release number of selected component (if applicable): Red Hat Virtualization Host 4.2.7 (el7.6) host and vm must be with RHEL - 7.6 - 7.0.el7 How reproducible: Always Steps to Reproduce: 1. Create a VM with RHEL - 7.6 - 7.0.el7 and disable memory balloon device 2. Run the VM 3. Expand VM memory using memory hot-plug Actual results: From the engine, the memory seems to expand. However, when connected to the guest the memory size remains the same. Expected results: The memory expanded Additional info:
