[libvirt-users] RHEL 7.x Guests Unable to Detect Any Storage Disks
by James Stanley 13 Jun '16

13 Jun '16

Greetings, I have been troubleshooting an issue in my RHEL 7.x guests the last few days where I am unable to get any attached storage volumes detected. I've tried various formats (raw, qed, qcow2) as well as some different cache settings but I've not had any luck getting the guests to see the disks. Are you aware of any bugs around this? We've had problems with RHEL 7.x in other virtualization environments mostly due to networking problems, but I've never encountered a situation where storage doesn't show up under /dev or /dev/disk/by-*. For reference, here's an example volume entry in the domain's xml: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/image-mnt/storage/vol0'/> <target dev='sda' bus='scsi'/> <shareable/> <serial>12536725</serial> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> And here's how the volume is defined: <volume type='file'> <name>vol0</name> <key>/image-mnt/storage/vol0</key> <source> </source> <capacity unit='bytes'>24696061952</capacity> <allocation unit='bytes'>24696066048</allocation> <target> <path>/image-mnt/storage/vol0</path> <format type='raw'/> <permissions> <mode>0600</mode> <owner>187</owner> <group>474</group> </permissions> <timestamps> <atime>1465847232.644199995</atime> <mtime>1465846963.996202455</mtime> <ctime>1465846963.996202455</ctime> </timestamps> </target> </volume> Thanks for your help.

[libvirt-users] vhba and storage pool creation
by Johan Kragsterman 12 Jun '16

12 Jun '16

Hi! Got a couple of storage questions here. I'm a storage guy, running a new project, and just started with libvirt, but have been using qemu/kvm on other platforms before, as well as oVirt. So, my questions here: I started with creating a vhba, and that went fine, I could see it on the storage side logging in to the target with its wwn. My next step would be to make it persistent, and then its this storage pool creation I've seen. Though some things are not clear to me. This is what the xml file looks like in the documentation: <pool type='scsi'> <name>poolvhba0</name> <source> <adapter type='fc_host' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> </source> <target> <path>/dev/disk/by-path</path> <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> So there are a few of these things that are unclear to me: * It seems like I should NOT configure a vhba in advance, but this is the process that will configure the vhba for me? * It also seems like the wwnn and wwpn set here are the ones that the vhba will use, not the parent hba? * There is an option of setting the parent here as well, which I will need for some resons, but it is unclear to me whether the wwnn and wwpn's are from the parent or the vhba? Looks like this in documentation: <source> <adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> </source> * So, are these wwpn and wwnn's from parent or vhba? * Lastly, the path: In the xml file it says /dev/disk/by-path...but I have no path...? Since I have not yet configured the vhba, I can not have a path? I can not map a lun to the vhba before I have a vhba... Or should I create a non persistent vhba, map a lun to it, and then source that path, use the wwpn and wwnn from that vhba in the scsi pool creation??? That would make sense, but also be a bit complicated to use... Best regards from/Med vänliga hälsningar från Johan Kragsterman Capvert

[libvirt-users] How to use PHP libvirt_connect?
by Phill Edwards 12 Jun '16

12 Jun '16

I'm having a go at writing some PHP scripts to do simple things like view the status of VMs running on my Ubuntu KVM host. I've installed php_libvirt_php but am failing at the first hurdle at the moment as I can't get the PHP script to connect. My normal way of connecting virsh from the command line is like this: $ virsh -c qemu+ssh://localhost/system This asks for a password which is fine as I'm doing it from the command line. I can't get a connection when I use other protocols: $ virsh -c qemu+tcp://192.168.0.103/system error: failed to connect to the hypervisor error: unable to connect to server at '192.168.0.103:16509': Connection refused I've tried using various $uri values for libvirt_connect but I get connection errors: $uri="qemu+tcp://localhost/system"; Connecting to libvirt (URI:qemu+tcp://localhost/system) *Warning*: libvirt_connect(): unable to connect to server at 'localhost:16509': Connection refused in */var/www/html/libvirt_test1.php* on line *8* Libvirt last error: unable to connect to server at 'localhost:16509': Connection refused $uri="qemu://localhost/system"; Connecting to libvirt (URI:qemu://localhost/system) *Warning*: libvirt_connect(): Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory in */var/www/html/libvirt_test1.php* on line *8* Libvirt last error: Cannot read CA certificate '/etc/pki/CA/cacert.pem': No such file or directory $uri="qemu+tcp://localhost/system"; Connecting to libvirt (URI:qemu+tcp://localhost/system) *Warning*: libvirt_connect(): unable to connect to server at 'localhost:16509': Connection refused in */var/www/html/libvirt_test1.php* on line *8* Libvirt last error: unable to connect to server at 'localhost:16509': Connection refused Presumably the answer is to 1) either allow connections that don't require SSH, or 2) somehow allow a password-less SSH connection from the www-data user that's running the PHP script. 2) sounds like it might be very difficult, and I don't know how to do 1) as I've only ever connected this way with SSH. Can anyone please provide some advise on getting this working.

[libvirt-users] Prevent guest to host CPU overloads
by Joan Aymà 09 Jun '16

09 Jun '16

Hello, I have a domain on a host that makes it to get on a overload, i.g. host stops responding. The host is a Fedora 22 with follow packages: QEMU emulator version 2.3.0 libvirtd (libvirt) 1.2.13.1 VM is a MS Windows environment... I followed some info on libvirtd wiki but cannot get the idea to limit guest resources into libvirt or get guest limits to enforce host has priority. Must iothread and iops limits be sufficient? I attach some domain info. Thanks in advance.

[libvirt-users] Java Application on 64bit Windows
by mehmet ayar 09 Jun '16

09 Jun '16

Hi, I am trying to develop a Java application with libvirt 0.5.1. I am trying this on Windows7 64bit. I downladed libvirt-0.5.1.jar and jna.jar files and added them to the Buildpath. Then I installed VirtViewer for windows 64 bit and copied dll files. In my application if i only use System.setProperty("jna.library.path", PATH_TO_DLL); then i see "UnsatisfiedLinkError: Unable to load library 'virt'" error. If i also use System.load(PATH_TO_DLL); then i see "UnsatisfiedLinkError:PATH_TO_DLL: Can't find dependent libraries" I searched everything in internet but couldn't find the same error with dependent libraries. What's missing in my setup? and why just setting jna path won't work for me, as it seems like worked on others. any help will welcome. regards,Memed

[libvirt-users] Migration command regression as of 1.3.4
by Brian Rak 09 Jun '16

09 Jun '16

Per the documentation, https://libvirt.org/migration.html#scenarionativedirect , 'virsh migrate domain dest interface' was a support command. As of 1.3.4 (when compression support was added), it's not. For example: # virsh migrate test qemu+ssh://10.0.0.1/system tcp://10.0.0.1/ error: invalid argument: Unsupported compression method 'tcp://10.0.0.1/' It seems like the compression code is grabbing the last argument now. Was this intentional? If so, what is the new command format? When will the documentation be updated?

[libvirt-users] Problem with USB pass through after switching to Xenial from Trusty
by Dale Amon 09 Jun '16

09 Jun '16

I use a virtual machine for a scanner I have for which the vendor never updated their driver. I have accessed it for years using a pass through: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x055f'/> <product id='0x040b'/> </source> </hostdev> I brought this over from the old config and although the machine boots as if it sees it, all I get with an lsusb it that the VM's usb hub exists. The scanner is showing on the host machine. I tried deleting the device and remapping it in virt-manager and then restarting the vm. No joy. So what has changed, or was there something I may have had to do 4 years ago to set this up that I have long forgotten? Perhaps some hack in udev on the host? I really need access to this scanner... like 4 hours ago!

[libvirt-users] unable to connect with virt-v2v to VMWare
by Cam Mac 08 Jun '16

08 Jun '16

Hi, I am trying to import and convert some VMWare guests from a VMWare cluster with vCenter version 6, to a KVM (oVirt) host. The KVM node (RHEL 7.2) has virt-v2v 1.28.1, though I've also tried using Fedora 23 which has 1.32.4. The details are: vCenter server: nssesxi-mgmt Datacenter name: North Sutton Street esxi server which runs the VM: nssesxi-mgmt04 folder name: Systems VM name: wvm2 cluster name: nssesxi Unfortunately, spaces were put in the name of the datacenter, so I escape them with %20 I authenticate against a AD domain (ARDA) with user 'cam' So the final URI is constructed as: vpx://<DOMAIN\user@<vcenter_server>/<folder>/<datacenter_name>/<esxi_server> <vm_name> The error I get is: # virt-v2v -v -x -ic vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1 wvm2 virt-v2v: libguestfs 1.28.1 (x86_64) [ 0.0] Opening the source -i libvirt -ic vpx://ARDA%5ccam@nssesxi-mgmt /Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1 wvm2 input_libvirt_vcenter_https: source: scheme vpx server nssesxi-mgmt Enter ARDA\cam's password for nssesxi-mgmt: libvirt: ESX Driver error : internal error: Could not find compute resource specified in '/Systems/North Sutton Street/nssesxi04-mgmt' virt-v2v: error: internal error: invalid argument: cannot open libvirt connection 'vpx://ARDA%5ccam@nssesxi-mgmt /Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1' If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] # # virsh -c 'vpx://ARDA%5ccam@nssesxi-mgmt/Systems/North%20Sutton%20Street/nssesxi04-mgmt?no_verify=1' list --all Enter ARDA\cam's password for nssesxi-mgmt: error: failed to connect to the hypervisor error: internal error: Could not find compute resource specified in '/Systems/North Sutton Street/nssesxi04-mgmt' # I can access via http a list of VMs at the following URL: https://nssesxi-mgmt/folder?dcPath=North%2520Sutton%2520Street&dsName=nsses… Below is the URI to the vm itself (once shutdown, it gets the name 'vm2_1'): https://nssesxi-mgmt/folder/wvm2_1?dcPath=North%2520Sutton%2520Street&dsNam… Any idea why the virsh and virt-v2v stuff doesn't work?
