[libvirt-users] Libvirt node is not getting booted through network with KVM too
by Varun Bhatnagar 18 Jan '13

18 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 18 Jan '13

18 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.

Hi, Earlier I was having libvirt-0.7.5 but now I have installed 0.9.8 version of libvirt now. I am trying to start libvirt daemon using the command below but daemon it is not getting started and the PID file is not getting created. Tried /usr/loval/sbin/libvirtd -d option too. In that case I am not getting any error but PID file is not getting created in this case too. /usr/local/sbin/libvirtd 2013-01-16 16:43:53.399+0000: 4070: info : libvirt version: 0.9.8 2013-01-16 16:43:53.399+0000: 4070: error : virCommandWait:2192 : internal error Child process (/usr/sbin/iptables --table mangle --delete POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill) status unexpected: exit status 2 2013-01-16 16:43:53.406+0000: 4070: error : virCommandWait:2192 : internal error Child process (/usr/sbin/iptables --table mangle --insert POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill) status unexpected: exit status 2 2013-01-16 16:43:53.406+0000: 4070: warning : networkAddGeneralIptablesRules:1259 : Could not add rule to fixup DHCP response checksums on network 'default'. 2013-01-16 16:43:53.406+0000: 4070: warning : networkAddGeneralIptablesRules:1260 : May need to update iptables package & kernel to support CHECKSUM rule. 2013-01-16 16:43:54.704+0000: 4070: error : umlStartup:471 : cannot initialize inotify 2013-01-16 16:43:54.704+0000: 4070: error : virStateInitialize:854 : Initialization of UML state driver failed 2013-01-16 16:43:54.704+0000: 4070: error : daemonRunStateInit:1157 : Driver state initialization failed and I am also trying to connect to VMPlayer with the following URL but it is giving the following error message: virsh # connect vmplayer:///session error: Failed to connect to the hypervisor error: Failed to connect socket to '/usr/local/var/run/libvirt/libvirt-sock': No such file or directory Is this because of the daemon, as it is not getting started or because of some other reason?

[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

[libvirt-users] A issue about KVM block migration
by 刘基 16 Jan '13

16 Jan '13

Hello everyone, I have a issue about the KVM block migration. Please give me some help. 1) I use the "virsh create" command to start a KVM VM in source machine. 2) And then, I use "virsh migrate" cammand to start a block migration: # virsh migrate --live --copy-storage-all --verbose win7 qemu+ssh:// 186.100.8.136/system root(a)186.100.8.136's password: Migration : [ 93% ] I execute "virsh list" command in source machine, and the result is: #virsh list Id Name State ----------------------------------------------------------- 1 win7 running I can find the corresponding qemu-kvm process in the result of "ps -ef | grep qemu-kvm" in source machine. And I execute "virsh list" command in destination machine, and the result is: #virsh list Id Name State ----------------------------------------------------------- 1 win7 paused 3) But after a few minutes，there have a error: # virsh migrate --live --copy-storage-all --verbose win7 qemu+ssh:// 186.100.8.136/system root(a)186.100.8.136's password: Migration : [ 97% ] error: Unable to read from monitor : Connection reset by peer. I execute "virsh list" command in source machine again, and the result is NULL. I cannot find the corresponding qemu-kvm process in the result of "ps -ef | grep qemu-kvm" in source machine. And I execute "virsh list" command in destination machine again, and the result is NULL. 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>
