[libvirt-users] Accessing a MAC address from inside the VM?
by David Lane 19 Apr '11

19 Apr '11

Greetings, I have a very simple problem, but the resolution is proving rather complex. Bare with me, I will attempt to explain. I have a host machine with no GUI. I attach an existing .img file to the host machine and need to change the MAC address (since the image was created on another machine). Is there a way from with in the guest to do this or do I have muck with the XML? And if I muck with the XML and change it, how do I pass this information up to the guest, or will the guest see it automagically or do I have to write it down and then manually transfer it into the guest's ifcfg? Using the GUI, when you change the NIC, the guest generally does not see the new MAC and grouses until you change it. Thanks. DAVID

[libvirt-users] USB2 passthrough
by Marco van Beek 18 Apr '11

18 Apr '11

Hi, I am trying to get a USB device working on a Windows 7 virtual machine, and it needs USB2 to work, so the USB passthrough does not work. I have searched for an answer and either the answer is so obvious I am being thick, or too complicated for anyone to address it. Can I simply do a PCI passthrough of a USB host controller? Would that then give me a whole load of USB2 ports I could connect to my computer? I would have to find out which port was connected to which controller, but surely it can't be that simple?

How do you modify the default network parameters? The net-edit command within virsh does not seem to work as expected. TIA

[libvirt-users] Problems setting up bridge
by Alex 15 Apr '11

15 Apr '11

Hi, I have a fc14 box with two interfaces that I'm having some difficulty setting up a bridge properly. I have a few kvm guests set up and running, but I've switched from using NetworkManager to using standard networking with a bridge. I've modified the ifcfg-eth0 and created ifcfg-br0 as per the standard documentation, but I think I'm having routing problems. This is what the network looks like: [root@fc14 ~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 68.195.XXX.40 * 255.255.255.248 U 0 0 0 br0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth1 192.168.125.0 * 255.255.255.0 U 0 0 0 virbr0 link-local * 255.255.0.0 U 1003 0 0 eth1 link-local * 255.255.0.0 U 1004 0 0 br0 default ool-44c3c129.st 0.0.0.0 UG 0 0 0 br0 br0 Link encap:Ethernet HWaddr 40:61:86:4E:84:09 inet addr:68.195.XXX.42 Bcast:68.195.XXX.47 Mask:255.255.255.248 inet6 addr: fe80::a0e7:ecff:fefd:340a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3883 errors:0 dropped:0 overruns:0 frame:0 TX packets:3579 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1818327 (1.7 MiB) TX bytes:590720 (576.8 KiB) eth0 Link encap:Ethernet HWaddr 40:61:86:4E:84:09 inet6 addr: fe80::4261:86ff:fe4e:8409/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3891 errors:0 dropped:0 overruns:0 frame:0 TX packets:3551 errors:0 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:1873169 (1.7 MiB) TX bytes:588302 (574.5 KiB) Interrupt:42 eth1 Link encap:Ethernet HWaddr 00:0E:0C:3B:36:F4 inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20e:cff:fe3b:36f4/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7622 errors:0 dropped:0 overruns:0 frame:0 TX packets:6936 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1062687 (1.0 MiB) TX bytes:4304984 (4.1 MiB) virbr0 Link encap:Ethernet HWaddr E6:ED:D2:6E:58:5C inet addr:192.168.125.1 Bcast:192.168.125.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) vnet0 Link encap:Ethernet HWaddr FE:54:00:67:2C:4C inet6 addr: fe80::fc54:ff:fe67:2c4c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:5 errors:0 dropped:0 overruns:0 frame:0 TX packets:391 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:300 (300.0 b) TX bytes:23358 (22.8 KiB) I've left out the loopback for simplicity. The problem is that I can't reach the br0 device from a server on the eth1 device (the 192.168. network). Is this a routing issue? Should I also add the eth1 device to the bridge? If so, how would I do that? Also, can you explain under what circumstances a tun device would be used? Does that have any relation to bridging? Thanks, Alex

[libvirt-users] Where actually is the callback triggered?
by kadir yüceer 15 Apr '11

Hi all, Quick question: When the hypervisor triggers a callback which is registered for generic events, (assuming I'm connected through qemu+tcp) where exactly is the callback triggered? On the hypervisor host or on my host? Regards Kadir

Hi, Is there a way that we can add custom IP-Tables rules in a nat'd physical host? I need some custom rules mentioned in physical host to access some services in the guest systems. Any hints on this? Regards, Kurian Thayil.

[libvirt-users] Listing shut off domains
by None 11 Apr '11

11 Apr '11

Hi, I am in the process of migrating a system that was using KVM to VMWare Workstation. The original code needs to list all the domains available on the local machine, no matter what their state is. The problem is that the shut off domains are not shown by the virsh commands on the VMWare Workstation system. On the KVM system, with one shut off domain, I get this output: maxpower@sw ~$ virsh list --all Id Name State ---------------------------------- - 00042-my-domain shut off On the VMWare Workstation system, with one shut off domain, I get this output: maxpower@sw2 ~ $ virsh -c vmwarews:///session list --all Id Name State ---------------------------------- As soon as I power on the machine in VMWare, it appears in the output as running: maxpower@sw2 ~ $ virsh -c vmwarews:///session list --all Id Name State ---------------------------------- 14063 my-domain-1 running Is this a limitation of the Workstation driver? Is there a workaround of some sort that I haven't thought of? How can I get the entire domain list when using Workstation? Thanks for your input, Alexis

[libvirt-users] Python API - setting client certificate path
by Wojciech Gumularz 09 Apr '11

09 Apr '11

Hi there, I'm trying to establish a TLS connection to libvirtd with certificates verification from a python script. My question is quite simple: is it possible to set the client certificate/keyfile path from within a python script? or it has to be in /etc/pki/libvirt/... Thanks in advance for any help Wojciech Gumularz
