...ation to do a series of virsh commands using that template XML as a start. I know it sounds awkward, but there is really nothing in libvirt or virt-install to automate assignment of PCI devices to non-0 functions. > On Wed, Dec 26, 2018 at 2:57 PM Peter Crowther > <peter.crowther at melandra.com <mailto:peter.crowther at melandra.com>> wrote: > > On Wed, 26 Dec 2018 at 16:26, b f31415 <bf31415 at gmail.com > <mailto:bf31415 at gmail.com>> wrote: > > If not, is there a way with one of the virt command line tools > to creat...

You say you can ping but not ssh. If you install tcpdump on the VM, can you see the ping packets arriving and leaving? If not, I suspect an address collision - especially if ping continues to work with the VM shut down. If you can't ping, check the other end of your bridge. I'm more familiar with open vSwitch, but I'm somewhat concerned that your bridge definition doesn't include a

I’m using virt-install to spin up VMs. At times I have a need to spin up VMs which have 100s of interfaces. I ran into the PCI issue mentioned in this previous thread based on how virt-install assigns PCI addresses to interfaces: https://www.redhat.com/archives/libvirt-users/2018-December/msg00064.html Using the info mention there I was able to part hand / part sw re-write an XML where I

Hi, Is it possible that "virsh destroy" does not stop a domain ? I'm asking because i have some domains running in a two-node HA-Cluster (pacemaker). And sometimes one node get fenced (killed) because it couldn't stop a domain. That's very ugly. This is also the reason why i asked before what "virsh destroy" really does ? IIRC a kill -9 can't terminate a

...I would still need to configure some static routes. I will take a stab at doing an open or routed network today, but in the meantime, your thoughts and comments about my setup are still welcome and encouraged.

Hi, i have a two node cluster with virtual guests as resources. I'd like to snapshot the guests once in the night and thought i had a procedure. But i realize that things in a cluster are a bit more complicated than expected :-)) I will shutdown the guests to have a clean snapshot. I can shutdown the guests via pacemaker. But then arises the first problem: When i issue a "virsh

Hello Libvirt Users, I would like to setup a two node bare-metal cluster. I need to guidance on the network configuration. I have attached a small diagram, the same diagram can be seen here: https://i.imgur.com/SOk6a6G.png I would like to configure the following details: - Each node has a DHCP enabled guest network where VMs will run. (eg, *192.168.1.0/24 <http://192.168.1.0/24>* for

Why do you reckon this is to do with your virtualisation system (presumably qemu/kvm, though you don't say) rather than Windows 10?

Pacemaker always knows where its resources are running. Query it, stop the domain, then use the queried location as the host to which to issue the snapshot?

Specify the MAC address as part of the domain XML for the bootstrap node. See https://libvirt.org/formatdomain.html#elementsNICS. If using virt-install, set it as part of the --network option: "--network NETWORK,mac=12:34..." - Peter On Fri, 12 Jun 2020 at 18:07, Ian Pilcher <arequipeno@gmail.com> wrote: > Is it possible to configure libvirt to generate
