Hallo, I have one ups with snmp and any ups without snmp. Shutdown works while network online. But some batteries are empty, so that the communication break early. Howto force shutdown if nut-snmp Communications lost? My 1. suggestion was option DEADTIME, but seem to be information only. (s. below) Any suggestions? The last way would be a ugly cronjob (like: ping || shutdown). regards Heiko

Hi, I'm using qemu+ssh://username at hostname/system as the remote URI. Libvirt seems to be communicating fine until some 2 minutes (we poll every 5 seconds) and then it throws up RPC error and many counters are wrong. But if I collect on localhost the counters seems to be coming fine. Test and testvm are guests on the local machine where as Win8 and Ubuntu* are remote URI's connected

Hello list. I’m using samba4 authorization with debian 8 without any problems. But in debian 9 very same config causes problems - unable to change GID. Here is my smb.conf: [global] netbios name = testvm security = ADS workgroup = WRKGRP realm = EXAMPLE.COM password server = 172.24.0.253 wins server = 172.24.0.253 wins proxy = no

Background: ---------- I'm trying to debug a two-node pacemaker/corosync cluster where I want to be able to do live migration of KVM/qemu VMs. Storage is backed via dual-primary DRBD (yes, fencing is in place). When moving the VM between nodes via 'pcs resource move RES NODENAME', the live migration fails although pacemaker will shut down the VM and restart it on the other node.

i'm having difficulty running KVM virtual machines off of a glusterFS volume mounted using the glusterFS client. i am running centOS 6, 64-bit. i am using virt-install to create my images but encountering the following error: qemu: could not open disk image /mnt/myreplicatestvolume/testvm.img: Invalid argument (see below for a more lengthy version of the error) i have found an example of

Hello, I just upgraded some of my el6xen boxes to latest CentOS 6.7, Xen 4.4.3 and dom0 3.18.17 rpms, and noticed these new problems: 1) virt-manager fails to start with an error: "D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory" And indeed.. there was no such file.

HI I have installed puppet on a RHEL 6.x machine. When I try to start the puppet master service, it fails and when I check status it says - "puppet dead but subsys locked".

Hello, I have been struggling through the task of moving our infrastructure over to Xen VMs. We were initially using Ubuntu packages for both dom0 and our domUs, but experienced extreme instability so we moved to CentOS, which has been much more reliable for dom0. Since we already had a bunch of Ubuntu VMs, we left them using the Ubuntu 2.4.24-19-xen kernel, but this has turned out to be

Hi, my system got updated to libvirt 6.0.0 (from 5.6.0) this morning, and now I'm having problems starting VMs that make use of openvswitch portgroups.

I think performance is not just about your xml, the host system will have a bigger impact.

List, I have a number of Windows 2016 servers I am deploying, but I’m having some I/O performance issues. I have done all of the obvious things like virtio drivers, but am finding there is more performance to be found with hyper-v extensions, how we virtualize the hardware clock, and iothreads. I’m using ZVOLs to back the VM, and I’m using 4k block sizes, which seems to offer the best 4k random

I am starting an instance passing xml configuration like this. Contents inside my kickstart file is this *apt-get install vim --assume-yes* . But I think kickstart is not considered while booting instance though I am able to start instance. Please help. Thanks in advance "<domain type='xen'>" + " <name>testVM-server</name>"

Hello. I'm try to understand, why in case of 20 workers libvirt fully locked when runs qemu hook (when domain starts) virsh list freezes. As i understand in case of using more workers it utilized to run hooks too, but as i see in pstree only main libvirt process executes hook. Why this happening? pstree -a -p 6642 libvirtd,6642 -d -l ├─qemu,9272 /etc/libvirt/hooks/qemu testvm prepare begin -

I don't see any changes between 5.6.0 and now done to openvswitch in libvirt (apart from harmless code reworks towards glib). > > When I start a VM, I get this

Hi, I encounter a problem with Syslinux 5.00 I cannot really describe. So I created two small videos: Booting with Syslinux 5.00 (1.3 MB): <https://www.dropbox.com/s/b6g8cdf2t9v48c6/boot-syslinux5-fail.mp4> How I fixed the problem by downgrading to Syslinux 4.06 and how booting should look like (6.5 MB): <https://www.dropbox.com/s/lt7cpgfm0qvqtba/boot-syslinux5-how-i-fixed-it.mp4>
