similar to: Does libvirt-sanlock support network disk?

Hi Daniel, I got a question about lock manager, if I enable 'sanlock' in qemu.conf and uncomment 'auto_disk_leases = 1' in qemu-sanlock.conf then restart libvirtd service, libvirtd will be dead, I know I should also uncomment 'host_id = 1' in qemu-sanlock.conf, because I enable 'auto_disk_leases'. The question is the libvirtd must die due to a error users

Hello, I configured libvirtd with the sanlock lock manager plugin: # rpm -qa | egrep "libvirt-0|sanlock-[01]" libvirt-lock-sanlock-0.9.4-23.el6_2.4.x86_64 sanlock-1.8-2.el6.x86_64 libvirt-0.9.4-23.el6_2.4.x86_64 # egrep -v "^#|^$" /etc/libvirt/qemu-sanlock.conf auto_disk_leases = 1 disk_lease_dir = "/var/lib/libvirt/sanlock" host_id = 4 # mount | grep sanlock

Hello list, In short: I am experiencing a problem where trying to start a VM which is allready running on a different libvirt host. Starting it fails, thanks to sanlock, but the disk dies on the original hypervisor and the vms filesystem is rendered read-only. Long version: i have the following setup: Two machines (H1 and H2) using CentOS 6.2 with the packages:

Hello, I wonder what the "open error -1" / "release open_disk error" messages in sanlock.log actually mean. I saw these messages in the log on a KVM host that rebooted, and after running "/usr/sbin/virt-sanlock-cleanup" on that host. The resources where disks from 2 guests running on another KVM host. So in fact the disks are still in use, bot got cleaned up by

Hello Han, Thanks for the response. The XML option with qemu:commandline works if the device is added during the VM creation. But I would like to hot-plug the device to the running VM. I can add the device using the command line <virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0> But I would like to add the device using the XML file, like <virsh attach-device VM-Name

For the libvirt 5.8 release, I find that there is a new comment in qemu.conf: #slirp_helper = "/usr/bin/slirp-helper" It indicates that there is a slirp-helper to help setup slirp network. But I cannot find it even after I built the latest qemu(v4.1.0-1378-g98b2e3c9ab) and libvirt (v5.9.0-rc1-2-g73f91d659b). Could you please tell me where I can find that helper program? Thanks --

Hello, I'm using libvirt and sanlock on qemu-kvm guests. Each guest has it's own Logical Volume for it's root filesystem. Sanlock is configured and working and prevents me from starting the same VM twice on multiple nodes and corrupting it's root filesystem. Each VM's domain XML resides on 2 servers that share the LVM volume group over fiber channel. In testing, I noticed

Hi list, I would like to ask a clarification about how locking works. My test system is CentOS 7.7 with libvirt-4.5.0-23.el7_7.1.x86_64 Is was understanding that, by default, libvirt does not use any locks. From here [1]: "The out of the box configuration, however, currently uses the nop lock manager plugin". As "lock_manager" is commented in my qemu.conf file, I was

Hello, A compilation failure happened when I tried building libvirt latest code on rhel8 Version: gcc-8.3.1-4.5.el8.x86_64 libvirt v5.9.0-352-g5e939cea89 Steps: 1. Clone libvirt source code 2.

Hi Team, I am exploring "edu" device in QEMU to add my own custom device. I am able to add the device using the command line. Would it be possible to add the device using XML file through libvirt? -- Regards, Bharath

Hi all, I have a 2 node cluster that consists of the following: * 1 drbd/gfs2 partition that holds VM images and XML * Sanlock configured with the disk lease directory on the same drbd/gfs partition Everything is working well, aside from one small issue I ran into. When testing fencing, on one particular test GFS began replaying the journal for the remaining node, and in the middle of it

CentOS 6 Hi all, I am working on setting up sanlock + watchdog on a 2 node KVM pair. Sanlock is working beautifully and is preventing access to the VM disks by more than one process as it should across both boxes. I am attempting to test failure scenarios involving watchdog, but I am having a hard time getting it to actually reset the server. I am running wdmd with -D so I can see the
