[libvirt-users] virDomainMemoryStats call
by Parakkal, Navin S 18 Jul '12

18 Jul '12

Hi, I'm using the API virDomainMemoryStats to fetch memory stats for a domain/guest on Fedora 16/RHEL 6.3 . I don't get these counters filled up VIR_DOMAIN_MEMORY_STAT_UNUSED, VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON,VIR_DOMAIN_MEMORY_STAT_AVAILABLE , VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT and VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT. The version of libvirt 0.9.11 on Fedora 16 . How to get all the counters filled up ? Should I take a specific version of qemu or should I do some config settings so that these values are filled up ? P.S. Please copy me in reply Regards, Navin Parakkal HP Software

[libvirt-users] Attaching usb devices
by Mauricio Tavares 18 Jul '12

18 Jul '12

Is the only way to attach a usb device to a vm first specifying the device, <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x3080'/> <product id='0x1234'/> </source> </hostdev> and then booting the vm while the device is attached? Can't I attach/detach a USB device to the vm later? I did try the method suggested in http://david.wragg.org/blog/2009/03/usb-pass-through-with-libvirt-and-kvm.h… but did not have much luck. Also, can anyone explain me what happened in this log excerpt: husb: open device 1.18 husb: grabbed usb device 1.18 husb: config #1 need 1 husb: 1 interfaces claimed for configuration 1 husb: device 1.18 disconnected

[libvirt-users] Set IP for LXC-container through libvirt XML
by Timothy Klim 17 Jul '12

17 Jul '12

Hi! How I can set IP to container without using dhcp? From http://libvirt.org/formatnetwork.html I have: <network> <mac address='00:16:3E:5D:C7:9E'/> <ip address="192.168.122.1" netmask="255.255.255.0"> <dhcp> <range start="192.168.122.100" end="192.168.122.254" /> <host mac="00:16:3e:77:e2:ed" name="foo.example.com" ip="192.168.122.10" /> <host mac="00:16:3e:3e:a9:1a" name="bar.example.com" ip="192.168.122.11" /> </dhcp> </ip> <ip family="ipv6" address="2001:db8:ca2:2::1" prefix="64" /> </network> Can I just set IP for domain(lxc-container)? Thank you.

[libvirt-users] PCI passthrough troubles
by mike allison 14 Jul '12

14 Jul '12

Hello, I have been struggling as of late to successfully configure a pci passthrough using libvirt with kvm. Hoping someone can shed some light on the problem. Overall my experience with virtualization limited is so please forgive. The guest runs fine till passthrough is configured. I am using virt-manager. This has been tried on both a Fedora17 x86_64 and Arch Linux x86_64 build with pretty much identical errors. I have carefully reviewed my hardware and purchased vt-d enabled parts where needed. vt-d is enabled for my chipset, cpu and in it's enabled in the bios. on both systems I complied a custom kernel to enable DMA Remapping, PCI-stub and set CONFIG_INTEL_IOMMU_DEFAULT_ON=y using kernel boot param: intel_iommu=on (not sure if overkill) have kvm module option allow_unsafe_assigned_interrupts=1 selinux set to permissive mode in fedora. not used in arch when launching I 1) modprobe pci_stub, 2) virsh nodedev-dettach pci device, 3) load guest using virtmanager... it get the following the log outputs * libvirt error window* > Error starting domain: Unable to read from monitor: Connection reset by > peer > > Traceback (most recent call last): > File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in > cb_wrapper > callback(asyncjob, *args, **kwargs) > File "/usr/share/virt-manager/virtManager/asyncjob.py", line 66, in tmpcb > callback(*args, **kwargs) > File "/usr/share/virt-manager/virtManager/domain.py", line 1114, in > startup > self._backend.create() > File "/usr/lib/python2.7/site-packages/libvirt.py", line 620, in create > if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) > libvirtError: Unable to read from monitor: Connection reset by peer > */var/log/libvirt/qemu/AED-VM.log* > char device redirected to /dev/pts/3 > Failed to assign irq for "hostdev0": Input/output error > Perhaps you are assigning a device that shares an IRQ with another device? > */var/log/libvirt/libvirtd.log* > 2012-07-08 22:45:11.403+0000: 3773: warning : ebiptablesDriverInit:4157 : > Could not find 'ebtables' executable > 2012-07-08 22:45:11.442+0000: 3773: error : virSysinfoRead:767 : internal > error Failed to find path for dmidecode binary > 2012-07-08 22:45:17.710+0000: 3764: error : > virConnectNumOfInterfaces:10466 : this function is not supported by the > connection driver: virConnectNumOfInterfaces > 2012-07-08 22:46:13.494+0000: 3764: warning : qemuDomainObjTaint:1371 : > Domain id=1 name='AED-VM' uuid=8f2892d8-df3c-6e75-0fe5-42c1ecd7835d is > tainted: high-privileges > 2012-07-08 22:46:13.725+0000: 3762: error : qemuMonitorIORead:526 : Unable > to read from monitor: Connection reset by peer > 2012-07-08 22:46:13.725+0000: 3762: error : qemuMonitorIO:582 : internal > error event from unexpected fd -1!=21 / watch 9!=9 > 2012-07-08 22:48:51.281+0000: 4097: info : libvirt version: 0.9.13 > * dmesg* > [ 158.017387] virbr0: port 1(vnet0) entered forwarding state > [ 158.017395] virbr0: port 1(vnet0) entered forwarding state > [ 158.017615] ADDRCONF(NETDEV_CHANGE): virbr0: link becomes ready > [ 158.476879] assign device 0:3:2.0 > [ 158.477080] deassign device 0:3:2.0 > [ 158.719521] virbr0: port 1(vnet0) entered disabled state > [ 158.719673] device vnet0 left promiscuous mode > any help would be greatly appreciated. mike allison

Re: [libvirt-users] [ovs-discuss] OpenVswitch with KVM virtual machines
by Neha Jatav 12 Jul '12

12 Jul '12

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup: ____ ____ / VM1\______br0_______/ VM3\ \____/ | \____/ | _|_ /VM2\ \___/ VM1 & VM2 are of the same subnet. They can ping each other. The ping packets aren't seen at the controller probably because they are in the same subnet and they don't need a flow table entry. VM3 is in a different subnet. So, when I ping from VM1 to VM3 or viceversa, they aren't reachable to each other. However, the packets do not arrive at the controller at all. Could you suggest me what might possibly be wrong. This is how the bridge looks: $sudo ovs-vsctl br0 show Bridge "br0" Port "vnet1" Interface "vnet1" Port "br0" Interface "br0" type: internal Port "vnet0" Interface "vnet0" Port "vnet2" Interface "vnet2" ovs_version: "1.4.0" Thanks and Regards, Neha On 7/9/12 11:48 PM, "Neha Jatav" <jneha(a)yahoo-inc.com> wrote: > > >On 7/9/12 10:25 PM, "Ben Pfaff" <blp(a)nicira.com> wrote: > >>On Tue, Jul 10, 2012 at 01:46:07AM +0900, Neha Jatav wrote: >>> I have KVM installed on my Fedora 17 box.

[libvirt-users] Different SAS controller IDs
by Anton Nikiforov 12 Jul '12

12 Jul '12

Dear All, I have problem with setting up migration on Intel Multi-Flex server. The problem is that SAS controller IDs (and volume ids in /dev/disk/by-path directory) are different between nodes. For example on node0 i have: lrwxrwxrwx 1 root root 9 Jun 29 07:20 pci-0000:04:00.0-sas-0x500015500002040a-lun-0 -> ../../sda lrwxrwxrwx 1 root root 10 May 27 09:17 pci-0000:04:00.0-sas-0x500015500002040a-lun-0-part1 -> ../../sda1 ....... On node1 i have: lrwxrwxrwx 1 root root 9 Jul 12 21:19 /dev/disk/by-path/pci-0000:04:00.0-sas-0x5000155000020409-lun-0 -> ../../sda lrwxrwxrwx 1 root root 10 Jul 12 21:19 /dev/disk/by-path/pci-0000:04:00.0-sas-0x5000155000020409-lun-0-part1 -> ../../sda1 ........ Difference is in 0x500015500002040a and 0x5000155000020409 But this is the matter of migration falure because migration script cannot find needed volume. Is there any chance to fix it somehow? Best regards, Anton Nikiforov

[libvirt-users] Starting a program inside VM through libvirt
by Jørgen Nordmoen 12 Jul '12

12 Jul '12

Hi again. I was just wondering if there are any support for running programs inside a VM through libvirt. From what I can see in the API the only solution I found was connecting to the VM with openConsole and running the program I want. This however seems a bit tricky through Python and I was just wondering if there are any simpler solutions. Best regards. Jørgen
