hello,i got a error message when use virsh attach-interface for a vm: first, list the vm's interface,there's no interface now. virsh # domiflist ubuntum-124 Interface Type Source Model MAC ------------------------------------------------------- then,i did an attach-interface action: virsh # attach-interface ubuntum-124 bridge br0 --persistent Interface attached

I haven''t had much luck googling for this, but Im starting to suspect that I just don''t have the right search terms. When you boot a dom0 kernel, you get around 8 network interfaces in addition to the usual eth0. When you boot a domU kernel, you get only what you specify. Since I have some driver domains that require a dom0 kernel but don''t require all the vifs, is

Hi, Does anyone know of a way to get around this problem. I have several long running VMs running on an Ubuntu 14.10 host and for some reason I am getting errors when trying to migrate them to another host. If I restart the VM then the problem does not exist, however for various reasons that is not an option with the remaining VMs. root@comp001:~# /root/bin/vm_migrate.sh ws001 comp003 virsh

plain text document attachment (hvvm.patch) OK, some explaination is needed here. The goal of lguest with paravirt ops, is to have one kernel that can be loaded both as a host and a guest. To do this, we need to map an area in virtual memory that both the host and guest share. But I don't want any conflicts with the guest. One solution is just to do a single area for boot up, and then use the

Hi, It looks like that's the issue: # cat /var/lib/libvirt/dnsmasq/osc_mgmt.hostsfile 52:54:00:2c:85:92,192.168.80.1,openstack-controller-00 But it makes me wonder...libvirt should be generating and managing this file right? Do I need to edit this myself or should libvirt be updating this file? If so then why isn't it? On Mon, Oct 30, 2017 at 5:21 AM, Yalan Zhang

Trying to think this through, hope someone can lend a hand. I have 3 eths I want to bond together and that seems simple enough. eth0,1,2 <-> bond0 , though not sure how this would be for multiple ip addresses needed for the virtual machines... perhaps eth:0, eth:1 etc....to bond0:1, bond0:2 ? then I want to bridge to my virtual machines.... I am going to be using virtual machines, each

Hello.. I have a big problem and It seems I can''t solve it.. Scenario: Linux server , 2 eths (one for Lan (eth0), one for Internet (eth1)). I use NAT for LAN clients.. The internet eth is linked into a switch , along with 6 sdsl modems.. (256 kbit each link - most probably an htb on the other side).. So , I made 6 aliases to my eth1 with ip''s for the DSL connections ..

On a hypervisor with multiple interfaces, we'd like to make those interfaces available to each of multiple VMs. We have both bridged interfaces and SRIOV interfaces, no NAT interfaces. When we create a vm in virsh using an xml file with no network elements, but having interface elements, we get the interfaces in the vm, but the ordering of eth devices does not match the ordering on the

Hi, I encounter a problem that the eth can't be up in the VM by using VT-d. I boot the VM using "virsh create vt_d.xml". The VM could recongize the NIC which was assigned .then I do in VM as follows: #cat /sys/class/net/eth0/operstate down #ifconfig eth0 up #cat /sys/class/net/eth0/operstate down #ficonfig eth 10.100.0.5 #cat /sys/class/net/eth0/operstate down more system

Interested in bonding my 2 on board nics along with my add on card NIC for a total of 3. How would this work with the virtual machines? My eths/IPs ---> bond0, bond0:1, etc ---> ? ----> virbr0,virbr0:1 (each machine to have own IP address, one machine may have some virtual sites needing more than one ip, so multiple ips added to mix..) add something to the bond0 file, or just leave

I imagine some day in the near future there will be a switch to ipv6. I cannot imagine ever remembering the ip address then...crazy. My question, since i have never done ip6 stuff, is what does that mean on my webservers? Would I just need to replace my ip4 with ip6 in my eths, bonds, bridges, and configuration files...and copy out my iptables to ip6tables, and change the dns servers? all

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

I need to support 32GB of ram, the 32bit HV wont do this i guess. Can i run a 64bit HV with a 32bit Dom0 and a 32bit DomU? Also, i tried building a 64bit HV on a 32bit dom0 but it failed, is it not possible to build a 64bit HV on a 32bit dom0? ~Shaun _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
