[libvirt-users] How to run libvirtd as non root user
by Anshul Arora (akarora) 31 Jul '15

31 Jul '15

Team, I note that libvertd runs as root user that is against the least privilege security model. root 307278 1 0 Jun20 ? 04:16:46 /usr/sbin/libvirtd -listen Appreciate pointers to alternate options that user could configure as a potential mitigation plan? Thanks, -Anshul

[libvirt-users] libvirt-1.2.17 I can't define lxc container
by Marcin Mirosław 30 Jul '15

30 Jul '15

Hello! I'd like to set up my first lxc container using libvirt. I'd like to start using the simplest configuration and next add things I need. So I've got xml as below: <domain type='lxc'> <name>vm1</name> <memory>32768</memory> <os> <type>exe</type> <init>/init</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <features> <capabilities policy='on'> </capabilities> </features> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/opt/vm-1-root'/> <target dir='/'/> </filesystem> <interface type='network'> <source network='default'/> </interface> <console type='pty' /> </devices> </domain> When I try to define container I'm getting: virsh # define /tmp/vm1.xml error: Failed to define domain from /tmp/vm1.xml error: invalid argument: could not find capabilities for ostype=exe domaintype=lxc I can't also find similar problem using web search engine. Maybe someone here can give me advice?

[libvirt-users] Custom bios image for qemu
by Phil Tooley 30 Jul '15

30 Jul '15

Hello all, So I am trying to get a qemu guest to use a custom patched seabios image rather than the default /usr/share/qemu/bios.bin I have tried changing the domain config file to include either: <os> --SNIP-- <loader readonly='yes' type='rom'>/home/telemin/qemu/seabios_patched.bin</loader> </os> OR domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0' --SNIP-- <qemu:commandline> <qemu:arg value='-smbios'/> <qemu:arg value='file=/home/telemin/qemu/seabios_patched.bin'/> </qemu:commandline> --SNIP-- And neither of these approaches result in the new seabios_patched.bin being used. I am clearly missing something here, can anyone with some more experience tell me what it is please? Many Thanks Phil Tooley

[libvirt-users] libvirt events and Ruby's EventMachine
by Jonathan Barber 25 Jul '15

25 Jul '15

Hello, I'm trying to adopt the Ruby event example from here https://www.libvirt.org/ruby/examples/event_test.rb to use EventMachine (a library for writing event driven programs). I have attached my attempt, which appears subscribe to events but never executes the callbacks I provide. I know this because when I reset domains (virsh reset VM) I see messages appear from the Handlers::notify_readable(), which should then invoke Libvirt::event_invoke_handle_callback() - but the output from the callbacks never appears. Typical output from the program looks like: add_handle fd=11 events=1 add_timer interval=-1 :notify_readable id=0 fd=11 events=1 update_timer id=0 interval=0 :notify_readable id=0 fd=11 events=1 :notify_readable id=0 fd=11 events=1 ... When I enabled debugging by setting LIBVIRT_DEBUG to 1 the output from libvirt appears to be the same as event_test.rb (excluding memory addresses). Can anyone see where I'm going wrong? Many thanks -- Jonathan Barber <jonathan.barber(a)gmail.com>

[libvirt-users] global lock when executing hook scripts

[libvirt-users] Migrate KVM linux based VM to microsoft Hyper-v
by test comp 21 Jul '15

21 Jul '15

Hi, I am searching around this topic but didn't get any suitable link, can you guys please help with this. i have my linux based VM as .img which is built on top of VirtIO protocol and runs fine on KVM or qemu. i am trying to port the same on the Microsoft Hyper-V but it is not working. I get blank screen with no other actions, tried the same on virtual box also but result is same. i have converted the vm.img format to .vhd, .vhdx, .vmdk , .vdi using different tools like qemu-img , and other windows based tools. but no success. I am running hyper-v on windows 10. My existing linux based VM setup works on qemu both in Centos and windows, but other than that its not working on any other hyper visor. i am not sure whether i need to update My VM's drivers to support hyper-V. Please guide me in the right direction. Regards Roshan S

[libvirt-users] Hot Cloning - clone running Virtual Machines
by NoxDaFox 20 Jul '15

20 Jul '15

Greetings, I am running a test automation service which makes use of QEMU/KVM. As the tests run for few minutes, the time spent booting the OS (Windows) is quite a waste of resources so I decided to play a bit around the idea of hot cloning running VMs. Following an old discussion I found, I proceeded with saving the VM state through virsh save, edit its XML file with virsh save-image-edit and restore it through virsh restore. The problem comes when I try to change some specific fields in the XML. As I run several instances on the same server, I need to provide different names and UUIDs to avoid collisions. Unfortunately, libvirt forbids this operation issuing the following error message: error: unsupported configuration: Target domain uuid 7c85e288-88fe-43d2-8b9c-89af4c83c10a does not match source 62f28517-8601-4d2e-942c-a20d087f9f4a Same thing applies with the name field. Is this a limitation of the API or it is a designed protection mechanism? Would it be possible to overcome this limit? Thank you.

[libvirt-users] Can't figure out how to restart VM after making config changes in virt-manager
by KARR, DAVID 15 Jul '15

15 Jul '15

I finally figured out my VNC configuration, so I can now run virt-manager to inspect and manipulate my VM. I initially created the VM with "virt-install", but I haven't been able to see the console or do anything with it. When I ran virt-manager, I tried to configure the vcpus (1->4) and change the boot order (cdrom, then disk, as I created the VM with an ISO). When I made these changes, virt-manager said they would take effect on the next restart of the VM. So, then I tried to restart the VM from virt-manager. The "Run" button is disabled, so I assume that means it detects that the VM is running. I've tried clicking "Shut Down" and selecting "Reboot" from the dropdown, but neither of those seem to do anything. I've tried to view the console window, but I've only ever seen a black screen there. I believe some people mentioned that I should try sshing to the VM. I would do that if I could find an IP address or hostname that appears to correspond to this VM. The obvious, using the VM name, didn't work. I'm not sure what to do here.

[libvirt-users] So why does "destroy" not actually destroy?
by KARR, DAVID 15 Jul '15

15 Jul '15

I thought it odd that if I have a running VM and I do "virsh destroy" it results in a VM that is "shut off". To ACTUALLY destroy a VM, you have to follow that with "undefine". Could someone elaborate on how we ended up with these slightly confusing semantics?

[libvirt-users] Debug VM boot from ISO issues

I'm having trouble booting a VM from an ISO, but my problems may not be virtualization issues, just general confusion. I'm running virt-manager on Ubuntu, but I need to boot a VM with an ISO that is based on CentOS. Is that possible? How do I define the VM in virt-manager to boot from an ISO? I initially created the VM with virt-install, but I started over with virt-manager, and now I'm not sure how to specify the ISO to boot from.

[libvirt-users] IPMI in Libvirt
by Anderson Kaiser 14 Jul '15

14 Jul '15

Greetings all, I am looking for a solution to use IPMI (BMC) in with LibVirt (Virt-Manager). Actually there is a Customer behind this request as well. Trying to be short: We are looking for a Solution in OpenStack Environment. Customer wants to have the entire environment running in Virt-Manager (probably for a P.O.C or tests purposes). So here is what he is trying to do: http://red.ht/1HfNn9r This template you can find in the Red Hat's OpenStack Install Guide. So far so good. But OpenStack works with High Availability and in some moment of the procedure you have to create an IPMI (BMC) interface in order to Fence the HA Nodes and Controllers. (Just for curiosity in this first moment customer is setting the Nodes - Hypervisors - as Nested KVM - so he can use the VM as an Hypervisor as well). That said the 3 VMs which are the controller, and also the 2 nodes, should have an IPMI Interface. Is it possible to have it in KVM? I mean, seems that in SeaBIOS we already have this support: http://www.seabios.org/pipermail/seabios/2012-August/004405.html Also I found a Red Hat BugZilla regarding this request: https://bugzilla.redhat.com/show_bug.cgi?id=815136 . but it seems to be "abandoned" since the beginning. So the point is: - Is it possible to have a NIC or a Device emulating an IPMI (BMC) interface? - If yes, how can we export it to the VM? Maybe we can do a pass-trough if the hardware is available. But Lets think in a Notebook or a Desktop, for instance (we are working with a POC, remember?) and maybe the IPMI Interface could not be available or oesn't exist. I thought if it was possible to have some kind of IPMI NIC emulated and also an "brdge" and then an additional virtual network for this bridge. Am I going to far? ;-) Anderson Kaiser (RHCE, RHCVA) Team Lead - Red Hat Global Support Services Latin America Red Hat Inc,. akaiser(a)redhat.com Ph: +55 11 3529-6000 Red Hat Support: 0800-602-5222

Let the one already in place, and just add the missing ones. Existing ones won't cause troubles. > Do I type in the registy entries under [1] and [2] exactly using copy paste?

(IDE/SATA/SCSI/Virtio) One easy way to find out is to use lspci -nn in a Linux host running Qemu with your target configuration. For instance, for the IDE bus, you'll get something like: 00:01.1 IDE interface [0101]: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] [8086:7010] -- Pierre Schweitzer <pierre(a)reactos.org> System & Network Administrator Senior Kernel Developer ReactOS Deutschland e.V.

When partprobe properly works (ie encounters no error), it doesn't print anything to console, it just adds the appropriate entries in /dev.

Hi Vincent, I can access to the source physical machine but it is an almost 24h running machine. I heard about VMware P2V program. I've never used it, yet. I don't want to virtio. I want a booting W2k3. That's all. ;-) TIA, Ruzsi

Hi, I made a disk image with CloneZilla from the original physical machine. That image was restored on an iSCSI volume. It isn't booting. I got BSOD. I tried IDE, SATA, SCSI disk type without any success. I tried to using virtio driver and if I use my image+W2k3 install CD+virtio VFD the Windows repair console see the disk and I can use the repair console with my image but the windows not start (or not booting because the system disk can't be seen by original "registry"). The drivers from virtio VFD image were copied to Windows' Driver directory manually. I tried to use virt-win-reg: rattila@amd1:~$ virt-win-reg SJ-SIMISPC /dev/disk/by-path/<iSCSI-path>:simispc-lun-2: Engedély megtagadva at /usr/bin/virt-win-reg line 260. (it means: Permission denied.) What can I do changing the original driver to virtio (or IDE/SATA/SCSI in KVM)? I can't do anything with the physical machine so the only option is playing with the disk image. TIA, Ruzsi

[libvirt-users] libvirt beginner needs to create and start VMs entirely on command line
by KARR, DAVID 11 Jul '15

I'm a beginner to libvirt and creating VMs, for that matter. I have a set of specifications for VMs I need to create and log into, but I have to create them on an Ubuntu box that I only have ssh access to. I won't have desktop GUI access, although I do have dynamic port forwarding, so I can access a browser GUI from my desktop. Reading through the libvirt info, I see numerous mentions about using VNC to do additional work, but I won't be able to use VNC (not allowed within our firewall). I could use some advice on how to move forward with this. I've started at https://help.ubuntu.com/lts/serverguide/libvirt.html for initial information. I managed to create a disk image for my first VM, and I believe I created the first VM using an ISO (based on CentOS, I believe), but I'll probably have to rebuild that, because I think I have to configure networks on the VM, which I didn't do on initial creation. I was confused by the initial results from "virt-install", because it seemed to hang after a second or two (I posted this SO question about this: http://stackoverflow.com/questions/31302871/trouble-using-virt-install-on-u… ). The reply from this makes it seem like it was trying to present a GUI for next steps, but I of course never saw that. The VM appears to exist, but in a "shut off" state.
