[libvirt-users] virsh define function question
by zhanggp 19 Jul '12

19 Jul '12

Hi, How do I view the libvirt virsh domxml-to-native function implementation? I think this function contains some error. Because we use libvirt to manage some host and vms on vmware hypervisor. We use openenbula generate a template for libvirt ,such as my attachment windows2008.xml. but when i use domxml-to-native to convert xml file to vmware config file vmx as below. This may not be accurate. For example: 1. guestOs type : could I config this parameter in xml file ,so after domxml-to-native to vmware.vmx , guestOS in my vmx file is "windows7srv-64 ". And also my pciBridge disappeared ! So could someone help me and tell us about 'virsh-c the esx :/ /@host?no_verify=1 define windows2008.xml' function realization。 Thanks all! virsh # domxml-to-native vmware-vmx windows2008.xml .encoding = "UTF-8" config.version = "8" virtualHW.version = "7" guestOS = "other-64" uuid.bios = "42 11 25 27 fd b6 7b 6d-72 3f 75 c6 25 fe ef 3e" displayName = "windows2008" memsize = "2048" numvcpus = "2" sched.cpu.shares = "normal" ide0:0.present = "true" ide0:0.deviceType = "ata-hardDisk" ide0:0.fileName = "/vmfs/volumes/349969f9-070dee8d/./windows2008.vmdk" floppy0.present = "false" floppy1.present = "false" ethernet0.present = "true" ethernet0.virtualDev = "e1000" ethernet0.networkName = "VM Network" ethernet0.connectionType = "bridged" ethernet0.addressType = "vpx" ethernet0.generatedAddress = "00:50:56:91:00:07" svga.vramSize = "8388608" zhanggp --------------------------------------------------------------------------------------------------- Confidentiality Notice: The information contained in this e-mail and any accompanying attachment(s) is intended only for the use of the intended recipient and may be confidential and/or privileged of Neusoft Corporation, its subsidiaries and/or its affiliates.

[libvirt-users] Questions related to the snapshot
by lin tan 19 Jul '12

19 Jul '12

Hi, I faced two problems with the snapshot: First issue, I can use the snapshot functions via the virsh correctly such as snapshot-list. And when I removed the snapshot XML files from /var/lib/libvirt/qemu/snapshot/**/, I don't see the snapshot of the Virtual Machine any more. That's correct. But after I copying the XML files back, I can't see the the snapshot as well. Only if I restart my laptop can I see them. However, restarting is what I want to avoid. Because I wish I could utilize the functions in a server in the future. Does anyone have ideas about this, Did I do something wrong or it's a limitation. So far, I am using the qemu-img command to check the snapshot and do the revert without restarting my laptop. Because the snapshots are already embedded in the img file. Second issue, I find if I create the XML file of snapshot by using getXMLDesc and output to a new file in python, there is a slightly different. But, the new XML file can't be recognized even if I restart my laptop. The new XML file miss the attribute <active> as far as I can see, is it so important? Here is one example: The original XML in the default folder: <domainsnapshot> <name>Ex</name> <description>Snapshot of OS updates</description> <state>running</state> <parent> <name>1342427860</name> </parent> <creationTime>1342428835</creationTime> <domain> <uuid>2c853de2-6bba-ad26-bf05-0045e5f1beb9</uuid> </domain> <active>0</active> </domainsnapshot> The new XML file I created: <domainsnapshot> <name>Ex</name> <description>Snapshot of OS updates</description> <state>running</state> <parent> <name>1342427860</name> </parent> <creationTime>1342428835</creationTime> <domain> <uuid>2c853de2-6bba-ad26-bf05-0045e5f1beb9</uuid> </domain> </domainsnapshot> Thank you so much. Best Regards Tan

[libvirt-users] I can't virt-clone into an existing LVM now (ERROR: clone onto existing storage volume is not supported:) - i could in previous lbvirt versions? (deployment scripts no longer work...)
by Morgan Cox 18 Jul '12

18 Jul '12

Hi To deploy KVM vms I use a KVM template + script - which is cloned, then cloned again and resized - using virt-resize. i.e ---------------------------------------------------- virt-clone --original debian6template-DONTSTART --name NAME.test -f /dev/vgpool/NAME.test virsh vol-create-as vgpool NAME 8G virt-clone --original NAME.test --name NAME -f /dev/vgpool/NAME virt-resize --expand /dev/sda1 /dev/vgpool/NAME.test /dev/vgpool/NAME ---------------------------------------------------- The reason I clone twice is because I know that virt-clone does things to prep it for a new install, also the whole point was to be able to specify a size to be clone into (hence the use of virt-resize) This worked fine on our Ubuntu 11.10 server, however in Ubuntu 12.04 when I try to do the same I get the error 'ERROR Clone onto existing storage volume is not supported: '/dev/vgpool/test' If I can't virt-clone into an existing LVM I know I can clone once - then resize with LVM, then virt-resize into the partition (then virt-sysprep) - however the issue with that is that it is far more fiddly to mange... Previously could just make a 20GB partition and use virt-resize to expand into - using the above method I would have to increase the LVM to the value I want minus the size of the template.. i.e I have to specify - the amount to increase by, rather than the final size I want.... The templates also change size (when I update them, etc) which would mean re-writting the script after every update. Is there a way I can re-enable being able to virt-clone to an existing LVM partition ? As mentioned it works 100% fine in Ubuntu 10.04 Regards

[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.
