[libvirt-users] Not able to do ssh with libvirt
by varun bhatnagar 24 Jan '13

24 Jan '13

Hi, I am having issue while doing *ssh* to a virtual node through libvirt. The nodes's ip address is 192.168.82.1. When I am giving the command it is giving the following error message: *virsh# connect vbox+ssh://192.168.82.1/session* *Password:* *error: Failed to connect to the hypervisor* *error: End of ifle while reading data: sh: nc: command not found: Input/output error.* Can anyone tell me why am I facing this problem and how to resolve it. Thanks in advance.

Hi, Paolo, All, I read "virtio-scsi support proposal v2"(http://permalink.gmane.org/gmane.comp.emulators.libvirt/50428) Try to add a virtio-scsi with scsi-generic like this: <hostdev type='scsi'> <source> <adapter name='scsi_host0'/> <address type='scsi' bus='0' target='0' unit='0'/> </source> <target> <address type='scsi' controller='0' bus='0' target='0' unit='2'/> </target> </hostdev> But It turn out to be wrong, showing: error: Failed to define domain from rhel63ga error: XML error: unknown host device source address type 'scsi_host' I'd like to know how shall to add a virtio-scsi disk with scsi-generic option. Thanks~ -- Best regards, Cheng

Re: [libvirt-users] snapshot troubles
by Christian Schmidt 23 Jan '13

Hi Juergen, if you are using kvm/qemu with libvirt you can try to delete the snapshot with the qemu monitor commands. The general syntax is virsh qemu-monitor-command --hmp <domain> '<command> [...]' So you can try virsh qemu-monitor-command --hmp DOMINO1-prealloc 'info snapshots' and thne delete it with the provided snapshot ID virsh qemu-monitor-command --hmp DOMINO1-prealloc 'delvm <ID>' This will delete the snapshot from your diskimage.

[libvirt-users] snapshot troubles
by jurgen.depicker＠let.be 23 Jan '13

23 Jan '13

Dear all, I created some snapshots, a long time ago, using the xml description option, so the snapshots have a name with a space in it... Really a bad choice apparently, since it seems impossible to delete them now: I cannot find how to enter the snapshot name properly due to the space. Quotes don't seem to help; escaping the space doesn't help either. Anybody knows how to solve this? eg: snapshot-delete DOMINO1-prealloc --snapshotname 'W2K3-virgin install' error: Domain snapshot not found: no snapshot with matching name ''W2K3-virgin' (-> notive also the extra ' added ) root@VLET3:~# time virsh snapshot-delete DOMINO1-prealloc "W2K3-virgin\ install" error: unexpected data 'install' Thanks, Juergen

[libvirt-users] Fwd: problem with libvirt
by rakshith h p 22 Jan '13

22 Jan '13

HI, i'm rakshith from bangalore. I'm using libvirt in one of my work. I have a problem in using it.So i would request your guidance. I have a controller which uses libvirt to establish the connection to the managed nodes. After the connection is successful, if the network goes down, the control will indefinitely wait inside the libvirt mod functions. It will come out only after the network is back and required data is obtained. In this case i need to add time out and get the control back once the data is not available and throw an exception. Can u please tell if there is any way i can do it.Thanks in advance -- Thanks and regards Rakshith H P Mobile - +919844303929

[libvirt-users] Question about blkiotune.device_weight
by hzguanqiang 21 Jan '13

21 Jan '13

Hi, Hu Tao I noticed that in your patch about blkiotune.device_weight, You set the device blkio weight value between 100 and 1000. But from the kernel document, I see that the blkio weight can be set from 10 to 1000. Why do you limit the weight minimum to 100 rather than 10 ? Looking forward your explanation, thanks! -------------- Best regards! GuanQiang 2013-01-18

[libvirt-users] Problems with VM networking on Ubuntu Quantal
by Dale Amon 18 Jan '13

18 Jan '13

I have shifted some VM's to a new server running Quantal and have had a world of trouble. The first one was caused by issues with an apparently compiled in path in their apparmor version which forced VM pools to be in /srv or similar rather than where I wanted them. For now this was not a big issue, and thankfully the server where it would be a big time problem (there are individual drives per major customer or user) is Debian. But... I still have issues. The networking has changed considerably and although I can get my VM running, I cannot reach it. The new quantal machines give you something like this: br0 Link encap:Ethernet HWaddr **** inet addr:10.0.0.xx Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: *****/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 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 p6p1 Link encap:Ethernet HWaddr **** UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 virbr0 Link encap:Ethernet HWaddr **** inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 vnet0 Link encap:Ethernet HWaddr fe:54:00:84:3c:4f inet6 addr: fe80::fc54:ff:fe84:3c4f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 The VM machine has a static ip on the same network, ie 10.0.0.x. It worked fine on the old server but is not reachable (and cannot connect outward). Forwarding is turned on: cat /proc/sys/net/ipv4/ip_forward 1 The VM has eth0 Link encap:Ethernet HWaddr **** inet addr:10.0.0.xx Bcast:10.0.0.255 Mask:255.255.255.0 inet6 addr: *****/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 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 An attempt to ping from the VM to anything outside gives a "Destination host unreachable" message. It has been a long time since I set the old machine up, so I may well have forgotten some step.

[libvirt-users] Libvirt node is not getting booted through network with KVM too
by Varun Bhatnagar 17 Jan '13

17 Jan '13

Hi, Sorry for putting the images. Posting this question again. I am trying to boot my node through network with the following configuration (even with KVM it is not getting booted): < domain type='kvm'> < name>Node-2-3</name> < os> < type>hvm</type> < boot dev='network'/> < boot dev='hd'/> < /os> < memory>654321</memory> < vcpu>1</vcpu> < interface type='internal'> < source name='test1'/> < model type='am79c970a'/> < mac address='20:00:00:0F:03:01'/> < /interface> < interface type='internal'> < source name='test2'/> < model type='am79c970a'/> < mac address='20:00:00:0F:03:02'/> < /interface>  < interface type='bridge'> < source bridge='vboxtap0'/> < mac address='20:00:00:0F:03:03'/> < model type='am79c973'/> < /interface> < /domain> But I am getting an error message saying: Fatal: Could not read from the boot medium! System halted. Even my network setting is not getting reflected in the Virtualbox. Can you suggest me what is wrong with this configuration. I think to boot a node from network we need to define a boot server but where shall I add that, I am confused.... Any help will be appreciated. Thanks in advance.

[libvirt-users] firewalld, no dhcp and virsh
by Paul Wouters 17 Jan '13

17 Jan '13

On all of the networks I create, I really don't want libvirt/KVM/virt-manager to do any kind of DHCP. I'm currently using xml files to feed into libvirt via virsh, for example: <network> <name>192_0_1</name> <bridge name='swan01' stp='on' delay='0' /> <mac address='12:00:00:16:16:BA'/> <ip address='192.0.1.127' netmask='255.255.255.0'> </ip> </network> Running this through virsh net-define gives no errors, and virt-manager shows: DHCP Start: disabled DHCP End: disabled But any attempt at starting the network causes: Error starting network '192_0_1': failed to add iptables rule to allow DHCP requests from 'swan01' Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 117, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/network.py", line 82, in start self.net.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 2049, in create if ret == -1: raise libvirtError ('virNetworkCreate() failed', net=self) libvirtError: failed to add iptables rule to allow DHCP requests from 'swan01' I narrowed this down to the fact that firewalld was not running. So I guess there are two bugs: 1) when not specifying dhcp ranges in the xml, it should _not_ try to poke DHCP holes. 2) when firewalld is not running, it should perhaps log a warning, but not abort the network start.

[libvirt-users] LibVirt CPU problem
by Michael Beham 16 Jan '13

16 Jan '13

Hi, I´m testing to start a KVM-VM with different CPU settings and I get an weird error when I use the parameter: <cpu mode='host-model'> !! I have a AMD Opteron 4280 CPU, but in the VM, proc/cpuinfo shows me, that I´m using Intel core2duo cpu model T7700 and in the flag-line of proc/cpu the system is listing the svm-flag of AMD?!?! If I use <cpu mode='host-passthrough'> I get the right CPU-model listed in the VM! Anyone an idea why I get the wrong information with host-model? BTW some further information about used versions: LibVirt version is 0.9.12 qemu-kvm 1.0 Kernel 3.3.2 Cheers, Mike

But, when I only use qemu-kvm command not use libvirt, I can test block migration successfully (use qemu-kvm to create a VM, and exec "migrate -b -d xxx" command in qemu-kvm monitor to migrate). The version of libvirt is 1.0.1 and the version of qemu-kvm is 1.2.0 ( 1.2.2 is also have this issue). Please give me some help. How to solve the issue. Thanks a lot. **

[libvirt-users] libvirt RPC error
by Parakkal, Navin S 11 Jan '13

11 Jan '13

Hi, I'm using qemu+ssh://username@hostname/system as the remote URI. Libvirt seems to be communicating fine until some 2 minutes (we poll every 5 seconds) and then it throws up RPC error and many counters are wrong. But if I collect on localhost the counters seems to be coming fine. Test and testvm are guests on the local machine where as Win8 and Ubuntu* are remote URI's connected through ssh. What causes this error "libvir: RPC error : End of file while reading data: : Input/output error" and how do we fix it ? I've pasted the logfile inline.

[libvirt-users] Attaching an "Internal Address"
by Varun Bhatnagar 10 Jan '13

10 Jan '13

Hi, I am trying to attach an internal address to my domain. So for that I am defining the following syntax in my xml file: but it is giving the following error: Tried giving interface type as network but that is adding Host-only type interface. Can anyone please suggest what can be the possible solution. I think it is some problem with the source network. Do I have to define any internal network before in any interface? If yes then how? Any help will be appreciated. Thanks in advance.

[libvirt-users] Unable to connect to vmchannel on host when the VM is started via libvirt
by Kaiwei Fan 10 Jan '13

10 Jan '13

Hi experts, When I start a VM using "virsh create vm.xml", I'm not able to connect to the vmchannel from host. The process libvirtd is running as root (modified qemu.conf to set user/group to root) already. The connect just hangs there even after the guest VM is up and running. However, if I start the VM using kvm directly (with same arguments as libvirtd in `ps auxwww`), the connect to vmchannel goes though after the guest VM is up and running. The problem is observed on ubuntu 12.10 (libvirt 0.9.13), but not ubuntu 12.04 (libvirt 0.9.8). Anyone knows why is this and how to fix it? Any suggestion is appreciated. ubuntu 12.10: Linux linux-01 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ubuntu 12.04: Linux linux-06 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Content of vm.xml: <domain type="kvm"> <uuid>c548c477-af6f-4aee-9e7d-987d6620aa27</uuid> <name>instance-00</name> <memory>262144</memory> <vcpu>1</vcpu> <os> <type>hvm</type> <boot dev="hd"/> </os> <features> <acpi/> </features> <clock offset="utc"> <timer name="pit" tickpolicy="delay"/> <timer name="rtc" tickpolicy="catchup"/> </clock> <devices> <disk type="file" device="disk"> <driver name="qemu" type="qcow2" cache="none"/> <source file="/home/user/project/kvm/instance-00/disk"/> <target bus="virtio" dev="vda"/> </disk> <serial type="file"> <source path="/home/user/project/kvm/instance-00/console.log"/> </serial> <serial type="pty"/> <channel type="unix"> <source path="/home/user/project/kvm/instance-00/vmchannel.sock" mode="bind"/> <target type="virtio" name="org.qemu.guest_agent.0"/> </channel> <graphics type="vnc" port="5900" autoport="no" keymap="en-us" listen="127.0.0.1"/> </devices> </domain>

[libvirt-users] how to use libvirt
by tianwei zhang 09 Jan '13

09 Jan '13

Hi everyone: I am just a new user to libvirt. I installed libvirt as: ./configure make sudo make After that I run the program in the development guide. But it seems that the program is stuck in the function of virConnectOpenReadOnly. When I tried the command: virsh list --all, it is also stuck. So could anyone tell me what's wrong with this? Thank you so much Tianwei Zhang

[libvirt-users] Regarding the support of libvirt for shared memory
by achala joshi 04 Jan '13

04 Jan '13

Hello All, I want to use shared memory , but in virsh I am unable to provide the necessary options for use of shared memory. I want to have some scripts so that they can be included in the xml file so that each time the need is of shared memory , it can be directly used from there only. Thanks and Regards
