[libvirt-users] Insert/eject USB
by Leroy Tennison 08 Mar '17

08 Mar '17

Is it possible to insert and eject a USB image in kvm/qemu/libvirt or are the only dynamically changeable devices cdroms and floppies? I've searched the web and I'm either not looking for the right terms or it's obscure. I should mention that I'm not talking about a connecting a physical host USB drive to a guest image, I want to be able to use a qcow image as the source. The context is that I want to be able to revert a VM image back to a prior state (internal snapshot) when testing but be able to retain some data without having to go to the effort of transferring it across the network. I've excluded cdroms as an option because they are read-only (correct me if I'm wrong on this) and require some effort to (re)build. Floppy drives appear to be limited to 1.44M which makes sense but is very limiting. Network mounts (NFS, Samba, etc.) require a server supporting the selected style of filesystem sharing over the network. I'm not sure I want to find out what happens to filesystem passthrough when a revert is done (unless someone knows and it's beneficial). I tried creating a partition associated with the VM but not auto-mounted, even if I unmounted the partition before reverting its state was rolled back. I possibly could get exotic here by setting the immutable attribute after unmounting the partition but, again, I'm hoping for something a little simpler and more straightforward. If there's a workable option I haven't considered I'm open to that. Thanks for any input.

[libvirt-users] domain reinitalization detection
by Matczak, KrzysztofX 08 Mar '17

08 Mar '17

Hello I'm trying to find out how to detect if domain was destroyed and brought up between two time moments, let's call it reads. So far the best approach I could find is to compare domain ID from previous and current read. And this is my first question : is that reliable solution ? Or do you know any better ? And related question is how to resolve virDomainPtr into domain ID ? The only verified way of getting domain ID I know is to memorize it's UUID, then call virConnectListDomains , then iterate over all returned domain IDs and resolve each one's pointer using virDomainLookupByID , then get UUID by virDomainGetUUIDString get domain ID of matching UUID's . It seems too complex and I expect noticeable performance overhead, so looking for something lighter. I'm trying to get current domain ID using API function : char * virDomainGetMetadata (virDomainPtr domain, int type, const char * uri, unsigned int flags) I'm not sure it's relevant function, since domain ID is contained not in metadata subsection but in opening <domain> markup. In fact I wasn't even able to get any data using that function call since I don't know how to construct valid URI. Do you know any doc or examples explaining that ?

[libvirt-users] Bluetooth Device Support
by Max Ehrlich 02 Mar '17

02 Mar '17

Hi, I want to create a virtual hci device on my virtual machine. I have seen that qemu has options supporting this https://qemu.weilnetz.de/doc/qemu-doc.html#Bluetooth_0028R_0029-options and https://qemu.weilnetz.de/doc/qemu-doc.html#pcsys_005fusb Is there any support for these options in libvirt? I was not able to find anything in documentation so I added the qemu command line xml as follows <qemu:commandline> <qemu:arg value='-usbdevice'/> <qemu:arg value='bt:hci'/> <qemu:arg value='-bt'/> <qemu:arg value='hci,host'/> </qemu:commandline> but when I try to run my machine from virt-manager i get the following error: Error starting domain: internal error: process exited while connecting to monitor: 2017-02-28T21:25:51.735987Z qemu-system-x86_64: -device ich9-usb-ehci1,id=usb,bus=pcie.0,addr=0x1d.0x7: PCI: slot 29 function 7 not available for ich9-usb-ehci1, in use by ich9-usb-ehci1 this error does not appear if I remove the commandline xml nodes Does anyone have any guidance for troubleshooting this? If it helps at all, virsh -v gives 2.1.0, virt-manager about page lists 1.3.2 and qemu-system-x86_64 --help gives 2.6.1 I am running Ubuntu 16.10. thanks, Max Ehrlich

[libvirt-users] shutdown -r now hangs in qemu-/kvm-vm
by Dan Johansson 28 Feb '17

28 Feb '17

Since updating app-emulation/libvirt and/or app-emulation/qemu (both were updated at the same time) I have a problem executing "shutdown -r now" in the vm ("shutdown -h now" works fine). When I execute "shutdown -r now" in the vm the shutdown process runs perfect until "Remounting root-filesystem readonly" and than it hangs and I have to "Force Power Off" to reboot. Any suggestion what could be wrong and what I can do to solve it? -- Dan Johansson, *************************************************** This message is printed on 100% recycled electrons! ***************************************************

[libvirt-users] error : Failed to switch root mount into slave mode: Permission denied
by Kyle Peterson 27 Feb '17

27 Feb '17

libvirt-3.0.0 When attemping to create a virtual machine I receive the error "error : Failed to switch root mount into slave mode: Permission denied”. I’m attempting to run qemu/libvirt/virt-manager in an Arch Linux lxc container on a Ubuntu 16.04 host. The host uses zfs for its containers. The arch container is set up as a priveleged container. I do already have kvm/qemu/libvirt working in a Ubuntu container. The reason for the arch container is because I want to try a newer version of qemu/libvirt. I’m not finding anything on google about this error message. Any way to get around it?

[libvirt-users] "virsh list" hangs
by Yunchih Chen 24 Feb '17

24 Feb '17

`virsh list` hangs on my server that hosts a bunch of VMs. This might be due to the Debian upgrade I did on Feb 15, which upgrades `libvirt` from 2.4.0-1 to 3.0.0-2. I have tried restarting libvirtd for a few times, without luck. Attached below are some relevant logs; let me know if you need some more for debugging.

[libvirt-users] Determining domain job kind from job stats?
by Milan Zamazal 22 Feb '17

22 Feb '17

Hi, is there a reliable way to find out to what kind of job does the information returned from virDomainGetJobStats or provided in VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event callback belong to? I'm specifically interested in distinguishing host-to-host migration jobs (e.g. those started by virDomainMigrateToUri* functions) from other jobs. If there is no better way, I'm thinking about examining presence or values of certain fields in the stats. I'd be fine with that as long as I can be sure it's a reliable way to identify the job kind. Thanks, Milan

[libvirt-users] How to set manually starting date/time for guest kvm
by Matt Xtlm 22 Feb '17

22 Feb '17

Hi there, is there a way to set a guest to start with a specific date and time. (e.g. when guest boots, starting guest time should always be (2017-02-05T12:00:00)). I've tried something like this in my kvm domain: <clock offset='variable' adjustment='-86400' basis='localtime'> <timer name='rtc' tickpolicy='delay' track='guest'/> <timer name='pit' tickpolicy='delay'/> <timer name='hpet' present='no'/> </clock> However, i can't insert a specific date and time statement (like starting kvm with -rtc base="2017-02-05T12:00:00"). The date/time must be set before starting the vm and must always be the same. Cheers, Matt
