I have a small public IP block (/29) I'd like to populate with VM's from a single physical box running CentOS/5. I'd like to get some thoughts on the best way to setup networking to support this. I'm OK with setting up the virtual hosts. Any advice would be appreciated. TIA...

I'm looking for the best way to setup networking support for VM's. I have a small subnet with 6 routable IP's I can use on the Internet. So, I'd like to setup a host and have VM's on the public IP's. The computer I have has 4 NICs. I'd like to use one for a private 10.x.x.x and the others for the public facing VM's. Can I support 5 VM's with the three

Hi, I am using version libvirt on debian lenny from backports repository, version 0.7.6-1~bpo50+1, amd64. Th functionality of "virsh net-edit" command is not very clearly documented, and I think it should change a configuration of a running network. But I see it doesn't. So, I want to add new host, for example: #I have old configuration root at xxx:/etc/libvirt/qemu/networks#

Hi all, How do you add a VLAN tag to a libvirt SR-IOV VF network usingthe "virsh net-update" command? I couldn't find the section to passto the "virsh net-update" command to add the VLAN tag. I have the following libvirt network defined for a SR-IOV VF: <network>  <name>GE0-0-SRIOV-1</name>  <uuid>7bc67166-c78e-4bcf-89ee-377dd9086631</uuid> 

Hi all, I just ran into problem properly stopping a network. I have defined a network and network hook script to accomplish some preparations and cleanup. Testing my configuration (virsh net-start and virsh net-destroy) was successfully. Now I wanted to automate the lifecycle. Unfortunately I realized that an autostarted network has to be persistent and thus will not be destroyed (even if the

Hi all, I'm getting an error, and have failed to succeed in googling for help with it. I have an old VM that I created a while back (at least one reboot ago, possibly a kernel upgrade ago), and am now finding that it won't start due to a lack of the 'default' network. When I look for how to fix this, everyone seems to agree on the command: # virsh net-start default error:

Hi libvirt-user, If I run (as a normal user): virsh -c qemu:///session net-list --all virsh -c qemu:///session pool-list --all I see a default network and a default pool. And indeed, these appear in the persistent configuration. It seems these are created the first time libvirtd is (auto)started in qemu:///session mode. Is it possible to configure the attributes of the default network and

Hi guys, when I detach an interface from vm during boot (vm boot not finished), it always fail. I'm not sure if there is an existing bug. I have confirmed with someone that for disk, there is similar behavior, if this is also acceptable? # virsh destroy rhel7.2; virsh start rhel7.2 ;sleep 2; virsh detach-interface rhel7.2 network 52:54:00:98:c4:a0; sleep 2; virsh dumpxml rhel7.2 |grep

Dear All, When user uses `virsh net-define xmlfile` , User only define an xml file in `/etc/libvirt/qemu/networks`. I created an uuid and another bridge in related xml file. But I need to create the following files for my network: `default.addnhosts default.conf default.hostsfile virbr0.status` Question is , can I create them via cmd? --Best regards mohsen

Hi, I am using "virsh edit" to edit a domain. After edit it says >> Domain ubuntu18.04 XML configuration edited. However, reopening the domain with "virsh edit" shows old file. The domain is also turned off. $virsh list --all --persistent Id Name State ---------------------------------------------------- - ubuntu18.04

I looked around but could not find any info on how to expand a libvirt managed LVM storage pool. I do not see any virsh command to do it but I was successful using the vgexpand command to add some more storage once I destroyed the pools and then restarted it. I'd like to verify that this is the proper way to grow the storage in a libvirt LVM storage pool. And this brings up a second

Hi, All! I found a bug! When I start the default network, I got a error shown as below: [root@localhost ~]# virsh net-start default error: Failed to start network default error: error creating bridge interface virbr0: Operation not supported snapshot: 陈鸿圳/chenhongzhen@zhicloud.com 13662457180 020-38260999 020-38260988 www.zhicloud.com 广州市天河区黄埔大道西100号富力盈泰广场A座1011

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

Hi all, I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights. I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set: virsh # net-dumpxml nat_limit <network> <name>nat_limit</name>

So I notice that some operations by libvirt such as creating a snapshot actually change the source of the active disk image for a domain without requiring a restart of the vm. How can this be achieved manually? There are instances where I am manipulating files with qemu-img or virsh commands and afterward need to change what file the vm is using as its disk. One example is when deleting a

virsh provides net-start <netname-or-id> to activate an inactive network. Does virsh provide any way to do the exact converse? deactivate an active network without destroying, undefining, removing, ... Also - I am curious - what does activate actually do? What change in state of anything occurs? ( I read the document at http://libvirt.org/formatnetwork.html which

Hi all? I try to use gdb to debug libvirt's source code, but when I tend to create a domain with xml, it shows "error: internal error Network 'default' is not active", so I use the net-related commands as below."virsh # net-start defaulterror: Failed to start network defaulterror: Cannot open network interface control socket: Operation not permitted" Then I check
