Hi, virNodeGetCPUStats and virDomainGetCPUStats have same name in pyton binding as getCPUStats virDomainGetCPUStats gets called internally when we use the method getCPUStats. How do we access virNodeGetCPUStats? Regards, Harsha

[libvirt-users] nwfilter example for security
by Java 18 Sep '12

18 Sep '12

hi, libvirt folks, I'm trying to use libvirt's nwfilter to achieve two goals: 1, by default all ports are closed, means that the virtual machine is isolated. 2, only some selected ports are opened, for example, tcp 22 for ssh, tcp 80 for http web, udp 67 and 68 for dhcp. Can somebody drop me a simple example how to do this in libvirt? I'm using libvirt 0.10.1, the latest version. thanks.

[libvirt-users] Network inoperable with QEMU arm example image
by Larry Brown 18 Sep '12

18 Sep '12

I posted the following message a few days ago. Does anyone have a minute to look at the output of the troubleshooting tools and advise if they appear correct or if anything stands out as a problem? Or is there another valid direction to go in to find out why the network fails? I'm really stumped here and if there is no other direction to go in I'm dead in the water. So should I just start playing taps? "I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried several combinations of network setups using the GUI and none appear to work. Optimally I'd like to bridge to my primary interface (em1) and be able to pull an address and talk directly to my network so I can download packages etc while in the VM. I tried setting up networking in that fashion with: Source Device : em1 with macvtap Device Model: Hypervisor Default Source Mode: Bridge but alas I cannot pull dhcp nor can I set a static address and ping other interfaces on the network. It also appears that every time I start the VM it creates another vnetX interface. One of the troubleshooting pages I came across listed all the tools but nothing about what to look for: 1) virsh net-list --all Name State Autostart ----------------------------------------- default active yes 2) brctl show bridge name bridge id STP enabled interfaces virbr0 8000.52540029e6c7 yes virbr0-nic vnet0 vnet1 vnet2 vnet3 vnet4 3) sysctl net.bridge.bridge-nf-call-iptables sysctl net.bridge.bridge-nf-call-iptables = 1 4) iptables -L -v -n Chain INPUT (policy ACCEPT 767K packets, 189M bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT udp -- virbr0 * 0.0.0.0/0 0.0.0.0/0 udp dpt:53 0 0 ACCEPT tcp -- virbr0 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 0 0 ACCEPT udp -- virbr0 * 0.0.0.0/0 0.0.0.0/0 udp dpt:67 0 0 ACCEPT tcp -- virbr0 * 0.0.0.0/0 0.0.0.0/0 tcp dpt:67 Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 ACCEPT all -- * virbr0 0.0.0.0/0 192.168.122.0/24 state RELATED,ESTABLISHED 0 0 ACCEPT all -- virbr0 * 192.168.122.0/24 0.0.0.0/0 0 0 ACCEPT all -- virbr0 virbr0 0.0.0.0/0 0.0.0.0/0 0 0 REJECT all -- * virbr0 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable 0 0 REJECT all -- virbr0 * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT 532K packets, 79M bytes) pkts bytes target prot opt in out source destination 5) ps -ef | grep dnsmasq nobody 12382 1 0 Sep11 ? 00:00:00 /usr/sbin/dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override 6) ifconfig -a em1 Link encap:Ethernet HWaddr 00:19:B9:48:2B:BA inet addr:10.45.212.46 Bcast:10.45.212.255 Mask:255.255.255.0 inet6 addr: fe80::219:b9ff:fe48:2bba/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:19048593 errors:95686 dropped:154 overruns:0 frame:98437 TX packets:10619346 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:12559170813 (11.6 GiB) TX bytes:1700214519 (1.5 GiB) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2978074 errors:0 dropped:0 overruns:0 frame:0 TX packets:2978074 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:847201395 (807.9 MiB) TX bytes:847201395 (807.9 MiB) macvtap0 Link encap:Ethernet HWaddr 52:54:00:AC:7F:0C inet6 addr: fe80::5054:ff:feac:7f0c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:294814 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:42804350 (40.8 MiB) TX bytes:468 (468.0 b) virbr0 Link encap:Ethernet HWaddr 52:54:00:29:E6:C7 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:621 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:43217 (42.2 KiB) virbr0-nic Link encap:Ethernet HWaddr 52:54:00:29:E6:C7 BROADCAST 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:500 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) vnet0 Link encap:Ethernet HWaddr FE:54:00:AC:7F:0C BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:38159 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 b) TX bytes:1995337 (1.9 MiB) vnet1 Link encap:Ethernet HWaddr FE:54:00:AC:7F:0C BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:37299 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 b) TX bytes:1949439 (1.8 MiB) vnet2 Link encap:Ethernet HWaddr FE:54:00:AC:7F:0C BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:36154 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 b) TX bytes:1888745 (1.8 MiB) vnet3 Link encap:Ethernet HWaddr FE:54:00:AC:7F:0C BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:35068 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 b) TX bytes:1832375 (1.7 MiB) vnet4 Link encap:Ethernet HWaddr FE:54:00:AC:7F:0C BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:207 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 b) TX bytes:10896 (10.6 KiB) 7) cat /proc/sys/net/ipv4/ip_forward 1 Any help I can get to resolve this would be greatly appreciated.

[libvirt-users] network comanline to xml

hello, i start a kvm guest with the following comand line: kvm -hda myimage.img -m 1024 -smp 2 \ -net nic -net tap,ifname=tap0,script=no now a plan to start this via libvirt. I have try to set nat via the libvirt-manager but this doesn't connect to network. So i try to use bridge network via the GUI and get a "non supported" error when i use tap0 as "bridge device". How can i "convert" the "-net nic -net tap,ifname=tap0,script=no" to a valid libvirt-xml file? The following example is also buggy: <interface type='network'> <mac address='52:54:00:46:3e:70'/> <source network='default'/> <target dev='tap0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'$ </interface> thanks

[libvirt-users] How to disable dnsmasq from starting automatically with libvirtd
by Marwan Tanager 13 Sep '12

13 Sep '12

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can catch the PXE parameters. Note this output upon starting two VMs on two different subnets: ----------------------------------------------------------------------------- tail -n1 -f </var/log/syslog | egrep -i "dhcpd|dnsmasq-dhcp" Sep 13 05:11:25 host dhcpd: DHCPDISCOVER from 52:54:00:72:f0:e2 via virbr0 Sep 13 05:11:25 host dhcpd: DHCPDISCOVER from 52:54:00:2a:e0:a6 via virbr1 Sep 13 05:11:26 host dhcpd: DHCPOFFER on 192.168.122.194 to 52:54:00:72:f0:e2 via virbr0 Sep 13 05:11:26 host dhcpd: DHCPOFFER on 192.168.100.107 to 52:54:00:2a:e0:a6 via virbr1 Sep 13 05:11:27 host dhcpd: DHCPREQUEST for 192.168.122.194 (192.168.122.1) from 52:54:00:72:f0:e2 via virbr0 Sep 13 05:11:27 host dhcpd: DHCPACK on 192.168.122.194 to 52:54:00:72:f0:e2 via virbr0 Sep 13 05:11:28 host dnsmasq-dhcp[1882]: DHCPDISCOVER(virbr1) 52:54:00:2a:e0:a6 Sep 13 05:11:28 host dnsmasq-dhcp[1882]: DHCPOFFER(virbr1) 192.168.100.251 52:54:00:2a:e0:a6 Sep 13 05:11:28 host dhcpd: DHCPREQUEST for 192.168.100.251 (192.168.100.1) from 52:54:00:2a:e0:a6 via virbr1: unknown lease 192.168.100.251.

I haven't been able to see any trace of it in the init scripts, and my guessing is that it's started not as a service, but in an ad-hoc manner by libvirt-bin. Checking the dependencies of the libvirt-bin package, I've noticed that dnsmasq is among them. So, my question is whether, starting dnsmasq automatically is something that is hard coded in libvirt-bin or is it just started in some other way that I am not aware of? Any suggestions would be really appreciated. Thanks, Marwan

[libvirt-users] libvirtd on MacOS X

Hi, I am trying to run libvirtd on MacOS X, but for now without success. My hypervisor is VirtualBox. Libvirt is installed from ports system. Without libvirtd I can see my virtual machines: LIBVIRT_LOG_FILTERS=1:vbox virsh -c vbox:///session setlocale: No such file or directory 2012-09-13 08:56:43.937+0000: -1: info : libvirt version: 0.9.10 2012-09-13 08:56:43.937+0000: -1: debug : tryLoadOne:163 : Found VBoxXPCOMC.dylib in '/Applications/VirtualBox.app/Contents/MacOS' 2012-09-13 08:56:43.937+0000: -1: debug : vboxRegister:97 : VBoxCGlueInit found API version: 4.1.22 (4001022) 2012-09-13 08:56:43.937+0000: -1: debug : vboxRegister:129 : VirtualBox API version: 4.1 2012-09-13 08:56:43.953+0000: -1: debug : vboxOpen:1048 : in vboxOpen 2012-09-13 08:56:43.962+0000: -1: debug : vboxNetworkOpen:7319 : network initialized 2012-09-13 08:56:43.965+0000: -1: debug : vboxStorageOpen:8137 : vbox storage initialized Welcome to virsh, the virtualization interactive terminal.

Do I have to start libvirtd in the context of the user, to see the virtual machines? Thanks in advance for any advice, Waldemar
