[libvirt-users] Exploring linbvirt.
by cooldharma06 22 Oct '13

22 Oct '13

hi, i am started to exploring libvirt. i am using the version libvirt-1.1.3 and i want to know (or) find the path how the libvirt is creating VM with xen (libxl) in the source. Any guide or reference is available for this. How i can find the path of calling sequence for other operations(api). Guide me to get some idea on debugging the libvirt. Regards, cooldharma06

[libvirt-users] help with VM migration problem: getfd, SCM_RIGHTS
by Joe Linoff 22 Oct '13

22 Oct '13

Hi, I am getting the following error when I try to migrate two VM's on my network using virt-manager: Unable to migrate guest: internal error unable to execute QEMU command 'getfd': No file descriptor supplied via SCM_RIGHTS All of the other VM's work just fine. There are 18 and I tested all of them. Version info OS: CentOS 6.4 (2.6.32-358.23.2) [the hypervisors and the guests] Compiled against library: libvirt 0.10.2 Using library: libvirt 0.10.2 Using API: QEMU 0.10.2 Running hypervisor: QEMU 0.12.1 It looks like this might be related to bug 731243 in the red hat bug DB but that was for 0.9.4. If it is related to SELinux permissions, where can I look to fix it? I ran "sealert -a /var/log/audit/audit.log" on the source hypervisor, the destination hypervisor and on the VM itself but no alerts were reported. Any hints would be greatly appreciated, I am not sure what to try next. Thanks, Joe

[libvirt-users] Create RBD Format 2 disk images with qemu-image
by Jon 22 Oct '13

22 Oct '13

Hello, I would like to use RBD Format 2 images so I can take advantage of layering. However, when I use "qemu-img create -f rbd rbd:data/foo 10G", I get format 1 RBD images. (Actually, when I use the "-f rbd" flag, qemu-img core dumps, but it looks like that feature may have been deprecated [1]) Is there any way to have qemu-img create RBD Format 2 images or am I better off using `rbd` to create the image then booting from the disk and performing the install, etc.? Thanks for the assist. Best Regards, Jon A [1] http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-June/002131.html

[libvirt-users] [FWD: [Qemu-devel] KVM Forum 2013 presentations on Google+ (Hangouts on-air)]
by Daniel P. Berrange 18 Oct '13

FYI for those not able to visit KVM Forum this year, we're attempting to have presentations streaming via G+. No guarantees about success, since we're at mercy of the Hotel net connection, but if streaming fails we'll at least have recordings of all sessions to be uploaded afterwards. Keep an eye on the G+ community mentioned below if you want to try and catch any live sessions. We'll put info in there if we suceed in streaming. Also code reviews next week may be subject to delay, since the Red Hat libvirt team will be at the KVM Forum.

[libvirt-users] Building XML from working qemu command-line for ARM virtio
by Clark Laughlin 18 Oct '13

18 Oct '13

Hello, I've got a working QEMU command line that I am trying to get into a libvirt dom xml and using domxml-from-native doesn't seem to know how to handle all of it. It's for ARM using some new virtio syntax: qemu-system-arm -machine virt -cpu cortex-a15 -enable-kvm -m 512 -kernel mach-virt-guest-3.11-zImage -display none -serial stdio -netdev type=user,id=mynet -device virtio-net-device,netdev=mynet -drive index=0,id=mydrive,file=saucy-server-cloudimg-armhf.img -device virtio-blk-device,drive=mydrive -initrd saucy-server-cloudimg-armhf-initrd-lpae -append "console=ttyAMA0 root=/dev/vda" Does anyone have any suggestions for converting the rest of it, specifically the -netdev, -drive, and -device params? Here is what domxml-from-native gives: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>unnamed</name> <uuid>fab06af7-aa37-45ca-ac4b-85d9bec89e52</uuid> <memory unit='KiB'>524288</memory> <currentMemory unit='KiB'>524288</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type machine='virt'>hvm</type> <kernel>mach-virt-guest-3.11-zImage</kernel> <initrd>saucy-server-cloudimg-armhf-initrd-lpae</initrd> <cmdline>console=ttyAMA0 root=/dev/vda</cmdline> </os> <cpu mode='custom' match='exact'> <model fallback='allow'>cortex-a15</model> </cpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/home/linaro/ubuntu-cloud-image/qemu-system-arm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='saucy-server-cloudimg-armhf.img'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <controller type='ide' index='0'/> <controller type='usb' index='0'/> <serial type='stdio'> <target port='0'/> </serial> <console type='stdio'> <target type='serial' port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='sdl'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> <memballoon model='virtio'/> </devices> <qemu:commandline> <qemu:arg value='-display'/> <qemu:arg value='none'/> <qemu:arg value='-netdev'/> <qemu:arg value='type=user,id=mynet'/> <qemu:arg value='-device'/> <qemu:arg value='virtio-net-device,netdev=mynet'/> <qemu:arg value='-device'/> <qemu:arg value='virtio-blk-device,drive=mydrive'/> </qemu:commandline> </domain> Thank you, Clark L

[libvirt-users] libvirt_lxc: "reboot -f" causes libvirt_lxc process to stop, but domain is still "running" for libvirt
by Florian Klink 16 Oct '13

16 Oct '13

Hi, I have a libvirt_lxc system container (with systemd). After running "reboot -f" inside the container, I get "Rebooting.\n". htop shows that the libvirt_lxc and all subprocesses are stopped, but from libvirt api/virsh/virt-manager, the domain is still "running". So it looks like libvirtd doesn't detect that libvirt_lxc process was stopped... Florian

[libvirt-users] virDomainGetCPUStats missing in Java API bindings ?
by Atul Gosain 15 Oct '13

15 Oct '13

Hi All I am trying to get the performance statistics for KVM using Java bindings. I found some api's for getting memory stats but not able to find any for cpu stats. I found virDomainGetCPUStats which look like its going to return cpu stats for a VM at http://libvirt.org/html/libvirt-libvirt.html and http://libvirt.org/hvsupport.html . I couldnt find these methods getting called from java source too. Which libvirt version does Java API correspond to ? I m using Java API 0.5.1 . If i want to get the virDomainGetCPUStats which is available from 0.9.x versions of libvirt, whats the way to get it in Java API bindings. Thanks Atul

good day to all. i still have not solved my problem with event handling. currently i have following code void libvirt_eventloop_thr_func() { while(true) //TODO: stop somehow on exit { if(virEventRunDefaultImpl() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Failed to run event loop: %s\n", err && err->message ? err->message : "Unknown error"); } } } ... virSetErrorFunc(NULL, libvirt_error_handler); libvirt_connection = virConnectOpen("qemu:///system"); if (virEventRegisterDefaultImpl() < 0) { virErrorPtr err = virGetLastError(); fprintf(stderr, "Failed to register event implementation: %s\n", err && err->message ? err->message: "Unknown error"); return -1; } { int callback = virConnectDomainEventRegisterAny(libvirt_connection, NULL, VIR_DOMAIN_EVENT_ID_LIFECYCLE, VIR_DOMAIN_EVENT_CALLBACK(domain_event_handler), NULL, NULL); if(callback == -1) { std::cout<<"Error: failed to register domain event handle callback\n"; return -1; } } boost::thread(boost::bind(&libvirt_eventloop_thr_func)); ... libvirt_eventloop_thr_func() called, and locked on virEventRunDefaultImpl(), can it be called in thread, and if no, how should i use it correctly ? sorry for asking again, but i really can't solve it myself. thx in advance.

[libvirt-users] ps/2 mouse cannot be removed from guest
by Hisao Taguchi 13 Oct '13

13 Oct '13

Hi, I installed Solaris 11(x86_64) as a guest in Fedora 19 KVM host and it works well. It seems that Solaris 11 can recognize only USB mouse but cannot recognize PS/2 mouse. When a PS/2 mouse is attached to the solaris 11 guest, something conflict occured and the mouse pointer is not moving on the solaris desktop. So, I tried to remove the PS/2 mouse from the guest, but I cannot remove it using virt manager. The "remove" button is grayed out by virt manager. I have to edit the /etc/libvirt/qemu/xxx.xml file to remove it. Why is it prevented from removing the PS/2 mouse by virt manager? I hope it wil be fixed. -- hisao

[libvirt-users] Kvm Libvirt dirty page log facility
by hellen maziku 13 Oct '13

13 Oct '13

Greetings! I am new to kvm Libvirt and are writing a python script to get the number of pre-copy cycles during a remote vm migration given memory size M of a VM in MB, the page dirty rate R of a vm in MB/s. My question is on how to get the page dirty rate. Does kvm libvirt provide a dirty page log facility that provides user space with a bitmap of modified pages since the last call? And if yes, please kindly direct me on how to get started. I have searched and come across things like VIR_NODE_MEMORY_STATS and kvm_get_dirty_log(struct kvm *kvm, struct kvm_dirty_log *log, int *is_dirty), I do not know if these are the ones and if yes how I can use them. Thank you very much

[libvirt-users] pom for 0.5.1
by Daan Hoogland 11 Oct '13

11 Oct '13

H, I am using libvirt from maven using a nexus proxy pointing to http://www.libvirt.org/maven2/ It downloads the jar fine but is expecting libvirt-0.5.1.pom (and ...sha1). In the proxy only the jar appears. When I download and rename the pom to my local .m2 cache my build works fine. Is this a bug in the distribution of libvirt in its maven repo or is my dependency wrong somehow? Kind regards, Daan Hoogland

[libvirt-users] failing connections w/ virt-manager
by Stefan G. Weichinger 09 Oct '13

09 Oct '13

Greetings ... I already spent quite some time to debug this ... See the thread on gentoo-user ml for reference: http://permalink.gmane.org/gmane.linux.gentoo.user/270091 basically I get dropped connections when I try to edit a VM via virt-manager. Tested from my gentoo workstation and a fresh ubuntu installation inside a VM at my office. The server is a new and shiny gentoo box with (gentoo release-numbers): libvirt-1.1.2-r3 qemu-1.5.3 openssh-5.9_p1-r4 ... 64bit, lots of RAM and CPUs .. installed last week ... so no obvious cruft on there. plain ssh sessions work fine for me. I access the server over an IPSEC-VPN terminated on my pfsense-router and on the customers side there is a firewall. This firewall allows full access for my private subnet, TCP/UDP ports 1:65535 ... so there should be no restrictions. Another issue: the server runs with systemd-204-r1 ... maybe important. # systemctl status libvirtd libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib64/systemd/system/libvirtd.service; enabled) Active: active (running) since Do 2013-10-03 17:39:37 CEST; 13h ago Main PID: 1242 (libvirtd) CGroup: name=systemd:/system/libvirtd.service └─1242 /usr/sbin/libvirtd --listen Okt 03 17:39:38 jupiter libvirtd[1242]: [251B blob data] Okt 03 17:39:38 jupiter libvirtd[1242]: [254B blob data] Okt 03 17:39:38 jupiter libvirtd[1242]: [301B blob data] Okt 03 17:39:38 jupiter libvirtd[1242]: firewall tools were not found or cannot be used Okt 03 17:39:41 jupiter libvirtd[1242]: [338B blob data] Okt 03 17:39:41 jupiter libvirtd[1242]: failed to add iptables rule to allow DHCP requests from 'virbr0' Okt 03 17:41:07 jupiter libvirtd[1242]: No response from client 0x7fe8b0c19450 after 5 keepalive messages in 31 seconds Okt 04 06:35:28 jupiter libvirtd[1242]: No response from client 0x7fe8b0c171a0 after 5 keepalive messages in 32 seconds Okt 04 06:40:05 jupiter libvirtd[1242]: No response from client 0x7fe8b0c164e0 after 5 keepalive messages in 31 seconds Okt 04 06:58:36 jupiter libvirtd[1242]: No response from client 0x7fe8b0c17050 after 5 keepalive messages in 31 seconds What to install for the "firewall tools"?

You can do this with the built in dhcp server for the virtual network. The definition is passed to dnsmasq. ... <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:e2:ed" name="foo.example.com" ip="192.168.122.10" /> </dhcp> </ip> ...

[libvirt-users] network filter and openvswitch bridge
by Pavel Tokarev 07 Oct '13

07 Oct '13

Hello all! I try to use network filters for openvswitch interfaces. This is the xml configuration of my bridge interface <interface type='bridge'> <mac address='00:11:22:33:44:55'/> <source bridge='virbr1'/> <virtualport type='openvswitch'> <parameters interfaceid='0529d6b5-627c-4330-803f-0d7018e6d496'/> </virtualport> <model type='virtio'/> <filterref filter='myfilter'> <parameter name='IP' value='10.10.10.99'/> </filterref> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </interface> The filter 'myfilter' is defined. If I start a domain with this interface all ports are correctly added to the 'virbr1' bridge, plus libvirt creates firewall rules using ebtables tool. BUT ebtables controls linux bridges, not openvswich bridges. As far as I know OVS has its own tool to create firewall rules for its bridges - ovs-ofctl. How to make libvirt to use the right tool for creating firewall rules for OVS bridges? If I remove ebtables tool and try to start the domain, libvirt complains "cannot create rule since ebtables tool is missing." Thank you.

[libvirt-users] libvirt crash when using libxl (xen 4.3)
by dienet 06 Oct '13

Hi I was trying out the libxl backend of xen 4.3 with libvirt, but I found it very unstable and unusable. I'm in xen 4.3 dom0 and starting: 1. xen stuff: echo "Starting Xen..." /etc/init.d/xencommons start #/etc/init.d/xend start . /etc/rc.d/rc.xen_bridge start /etc/init.d/xendomains start #libvirtd -l -d hsflowd 2. Starting libvirt -v to see what is going on. After that I'm using virsh to do some simple tasks: virsh # list Id Name State ---------------------------------------------------- Where is dom0? virsh # create debian_pv.xml error: Failed to create domain from debian_pv.xml error: End of file while reading data: Input/output error error: One or more references were leaked after disconnect from the hypervisor error: Failed to reconnect to the
