[libvirt-users] way to see the bootmenu via serial?
by mail list 13 Feb '15

13 Feb '15

Maybe this should go to the qemu mail list, but I have domains configured to dump to serial. Works fine I see Grub menu/kernel messages and the like, but the "bootmenu" listing only shows up over vnc. Is there a way to have that show up over serial? I definitely can hit up the qemu mail list as well if inappropriate for here

[libvirt-users] spice session locking
by Jon Doe 13 Feb '15

13 Feb '15

Hi List, Is it possible to prevent other clients from stealing my libvirtd hosted spice session? This is a problem for me where multiple co-workers access the same guest over a qemu+ssh:// connection. Instead of simply disconnecting clients, I'd like libvirtd to deny the new client. I've been looking at polkit acl rules and the vnc sharePolicy attribute but so far no luck.

[libvirt-users] QEMU 2.2.0 managedsave: Unknown savevm section type 5
by Paul Apostolescu 13 Feb '15

13 Feb '15

Hello, I am running into issues restoring VMs during reboot for some of my XP VMs - the environment is QEMU 2.2.0, libvirt 1.2.12 on CentOS 6.5 with KVM and libvirt-guests is set to suspend at shutdown. The weird part is Windows 7 is restored properly from the managedsave however XP does not, doing a start from virsh shows this: virsh # start xp-check error: Failed to start domain xp-check error: internal error: early end of file from monitor: possible problem: Unknown savevm section type 5 2015-02-04T23:55:37.117515Z qemu-kvm: load of migration failed: Invalid argument (qemu-kvm is a link to qemu-system-x86_64). Any ideas how to fix this ? Thanks

[libvirt-users] vm live storage migration with snapshots
by Edward Young 13 Feb '15

13 Feb '15

Hi all, I'm investigating the ways to improve the live migration performance in libvirt. I have a question about the vm live storage migration. the platform is libvirt + qemu + kvm If we want to migrate a running vm with its virtual disk images to another node. we can use 'virsh migrate ....' commands. What if this vm has a number of disk-only external snapshots? In the current version, how can live migrate this vm? Is it possible to blockcommit the snapshots to the base image and later perform the migration, without shutting down the running vm? Or is it possible to iteratively transfer all the snapshots to the destination and later live migrate only the latest new data? Thanks in advance. Best, Ed

[libvirt-users] libvirt/virsh change boot order
by Robb Walker 11 Feb '15

11 Feb '15

Hello, hope all are well. Am I missing something? If I add a cdrom and change boot order in a running vm with virsh edit, I have to shutdown the vm and restart to see the change in boot order. I can not just restart the vm via reboot inside the vm or virsh reboot vm. I don't see anything under /var/lib/libvirt/qemu/saved where I might expect conflict if I was battling against a saved configuration. If obvious, DUH, apologies and virtually bonk me on the head. Note: This is actually okay. Just don't want to miss on something that would allow me to just cycle the vm after make changes. on ubu -- 14.04 ii libvirt-bin 1.2.2-0ubuntu13.1.9 amd64 programs for the libvirt library ii libvirt-dev 1.2.2-0ubuntu13.1.9 amd64 development files for the libvirt library ii libvirt-doc 1.2.2-0ubuntu13.1.9 all documentation for the libvirt library ii libvirt0 1.2.2-0ubuntu13.1.9 amd64 library for interfacing with different virtualization systems <os> <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type> <boot dev='cdrom'/> <boot dev='hd'/> </os> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/home/foo/Downloads/archlinux-2015.02.01-dual.iso'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> Thanks and Kind Regards all This e-mail and any attachments may contain information that is confidential and proprietary and otherwise protected from disclosure.

Re: [libvirt-users] libvirt 1.2.10 and latest EL6 qemu-kvm

(I'm sorry, I didn't find my original message but I provide the archive link: https://www.redhat.com/archives/libvirt-users/2015-January/msg00069.html ) I just tried the latest libvirt release (1.2.12), combined with the following qemu EL6 package from centos: qemu-kvm-0.12.1.2-2.448.el6_6.x86_64 Using 1.2.12 and this version of qemu-kvm, I still get the following error when trying to start a domain: error: Failed to start domain btcab0001ap.unix.banksys.be error: internal error: unable to execute QEMU command 'qom-list': The command qom-list has not been found The older qemu package (qemu-kvm-0.12.1.2-2.415.el6_5.14.x86_64) works just fine though (I also tried the qemu-rhev-packages for el6 from ovirt, but no change).

Re: [libvirt-users] About live migration with snapshots
by Edward Young 11 Feb '15

11 Feb '15

Hi All, Sorry, I do not know to reply the previous message directly, so I have to manually copy them here. I have two questions about the following issue? 1. I follow the instructions blew to migrate a vm with snapshots. When I perform 'virsh snapshot-create --redefine $dom file' on the destination.' I got an error saying that "no domain with matching name $dom". I'm wondering during the mgiration, what do we need to do in the destination? create a new base file? 2. What does the following instruction do? "you then loop over 'virsh snapshot-delete --metadata $dom $name' on the source, at which point, live migration will now work." 3. Also, could you explain a little about the high level techniques for this function. suppose we have a vm with one base file and two snapshots. How does the following instructions do to migrate all of them? Thanks!

It comes out a message "cannot migrate domain with 1 > snapshots" Unfortunately, figuring out how to migrate snapshot information at the libvirt API level requires some engineering work - the current RPC protocol for migration is not set up to migrate an arbitrary amount of snapshots in a single call. On the other hand, if you are allowed to make more than one API call, the solution is already available; maybe we should patch virsh to learn how to make the series of API calls, to automate what I will describe below. > > Then I try to trace the code(Libvirt 0.9.8 to 1.0.3), I find out the code > in src/qemu/qemu_migration.c @ Line 1395 - 1440 (Libvirt 1.0.3) It's still unimplemented at the libvirt level, even in libvirt.git. > > It will check the VM which has snapshots or not. > > I just curious about this limitation, why the VM can't live migration with > snapshots? Doing it all in one RPC call would be a potential denial-of-service (RPCs are bounded in length to avoid consuming server resources, and taking lots of snapshots on the source could easily be made to exceed bounds). If someone can design a way to set up a series of RPC handshakes, then we could do it at the libvirt level in a single API call, but I'm not sure it is worth it. > > What happen if I skip this check? > > Does it has any suggestion way or virsh command with options to do live > migration with snapshots? The existing solution at the management tool layer is to migrate the snapshot information first, and then to migrate the domain. For each snapshot in 'virsh snapshot-list --name $dom', you will want to 'virsh snapshot-dumpxml $dom $name > file' on the source, then 'virsh snapshot-create --redefine $dom file' on the destination. Next, determine 'virsh snapshot-current --name $dom' on the source, and use 'virsh snapshot-current $dom $name' on the destination to set it as current (if there is a current snapshot). After the destination has all the snapshots, you then loop over 'virsh snapshot-delete --metadata $dom $name' on the source, at which point, live migration will now work. Patches to teach virsh how to do all this work in a single 'virsh migrate' are welcome. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org *Attachment: signature.asc <https://www.redhat.com/archives/libvirt-users/2013-March/pgpmxFegVXm2O.pgp>* *Description:* OpenPGP digital signature

[libvirt-users] Possible to change 'machine type' attribute while vm is running?
by Andre Goree 09 Feb '15

09 Feb '15

Hello. I'd like to determine if it's possible to change the 'machine type' attribute while a vm is running. For example, I have: <os> <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type> <boot dev='hd'/> </os> I'd like to change that to "machine='pc-i440fx-1.7'" due to an error[1] I'm seeing while migrated similar images to another host. The only way I've been able to change the machine is by first shutting down the vm, making the change, then starting the vm back up. I'd like to avoid that if at all possible. I did find the tool "libvirt-migrate-qemu-machinetype", but it doesn't seem to do what I think it's intended to do -- i.e., it does NOT change the machine type, even after reboot. Perhaps I'm just using it wrong? I performed the following: root:~# libvirt-migrate-qemu-machinetype -t pc-i440fx-1.7 <domain> Waiting up to 10 seconds for libvirtd to start... Waiting up to 30 seconds for libvirtd to respond to requests... Checking domains defined in /etc/libvirt/qemu... Migration complete But the machine type remains the same after the above command has been run. Thanks in advance for any insight you can provide.

[libvirt-users] CPU model and type

Hello, Is there a way to configure the domain cpu in such a way that the info reported to the guest OS system will remain constant ? For example in older versions of of libvirt/qemu the cpu was reported as "QEMU Virtual CPU version (cpu64_rhel6)" but moving the vm on a qemu2.2.0 is is reported as "QEMU Virtual CPU version 2.2.0".

[libvirt-users] CPU model and missing AES-NI extension
by Dennis Jacobfeuerborn 06 Feb '15

06 Feb '15

Hi, today I tried to configure a guest using Virt-Manager and used the "copy host cpu configuration" option which resultet in a "Sandy Bridge" model. What I noticed is that for example the "aes" extension is not available in the guest even though it is available on the host cpu. This is what the host cpu looks like: model name : Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid And this is what I get in the guest: model name : Intel Xeon E312xx (Sandy Bridge) flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb lm constant_tsc pni ssse3 cx16 sse4_1 sse4_2 popcnt lahf_lm abm Is there a way to get closer to the hardware and get as many of the host features in the guest as possible?

How can I do port mirroring with sr-iov? vepa This network uses a macvtap "direct" connection in "vepa" mode to connect each guest to the network (this requires that the physical interfaces used be connected to a vepa-capable hardware switch. The physical interface to be used will be picked from among those listed in <interface>subelements of the <forward> element; multiple guest interfaces can share each physical interface (libvirt will attempt to balance usage between all available interfaces).Since 0.9.4

Hello, what happens when an instance writes data with 0% available physical disk space, on QCOW2 images for instance, apart from destruction and unpredictability? I'm aware that monitoring is mandatory in production environments, but are there other known industry tricks to deal with this? Soft/hard limit settings, autopause/stop, or does KVM react in doing force shut down the VM in question? Thank you, Fabrizio.

I try to assign 8 host cores to Windows 2003 Server Standard guest. Because this OS version has a limit of 4 sockets, I have to change the CPU topology. My guest definition: <vcpu>8</vcpu> <cpu match='minimum'> <model>core2duo</model> <topology sockets='4' cores='1' threads='2'/> </cpu> doesn't work as expected. I should have 4 CPUs in the Device Manager and 8 CPU charts in Task Manager, but I have the opposite. And no matter what numbers I set in the topology, the guest always detects 8 sockets.

[libvirt-users] Sr-iov passthrough - no packet arrive to guest
by Yaron Illouz 27 Jan '15

27 Jan '15

Hi I am trying to do passthrough to guest using sriov and libvirt I tried to use both techniques from here http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E <http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E> Assignment from a pool of SRIOV VFs in a libvirt <network> definition Assignment with <interface type='hostdev'> (SRIOV devices only) <network> <name>passthrough-eth6</name> <forward mode='hostdev' managed='yes'> <pf dev='eth6'/> </forward> </network> I launch the vm, there is a vm with virt-install .... --network network=passthrough-eth6 I inject traffic with a generator so I defined it in promisc mode without an ip address.(ifconfig eth6 promisc up) In my physical device eth6 i can see RX increasing. But in the guest side nothing arrive in the RX? Why? I don't know in which log to look at to understand the problem I defined the network-script/eth1 file in the guest is defined as static (not dhcp) as the interface it is connected to in host have no ip. I have a another interface on the host connected via ovs and libvirt and it is working fine - you can see it in log as vnet0(thanks to this mailing-list help). In the guest part I attached the log but I think interesting part is Jan 27 17:03:21 localhost kernel: ixgbevf 0000:00:04.0: NIC Link is Up, 10 Gbps I also attached dmesg output from guest Here is the log from the host side, I can't see an error. /var/log/message Jan 27 12:02:29 1235 avahi-daemon[2598]: Withdrawing address record for fe80::fc54:ff:fe92:7352 on vnet0.

[libvirt-users] live migration taking forever
by Xu (Simon) Chen 27 Jan '15

27 Jan '15

Hey folks, I am running libvirt 1.2.4 and qemu 2.1 on a 3.14.27 kernel. I've found that live migrating a relatively large VM (16 cores and 64G ram) is taking forever - close to 15 hours now, and still not done... With "lsof -i", I can see a connection is established from my source hypervisor to a target hypervisor, likely for the purpose of copying data. nettop shows that this connection is constantly sending 50-60MBps traffic. The VM being migrated has a disk on ceph by using librbd. I wonder if anyone has seen similar issues, and how I could troubleshoot further. (I tried but failed to get qemu monitor to work on the VM...) Thanks. -Simon

[libvirt-users] Probem with Windows 2012 R2 server
by Dominique Ramaekers 26 Jan '15

26 Jan '15

Hi, I'm having a lot of trouble with a Server 2012R2 evaluation version. I'm testing it to see how good it works in libvirt-kvm. It seems the server won't run longer than a few days. After a few days, when I shut down the server, she won't start again. Has anybody have experienced the same??? My Windows 8.1, and Linux VM's works perfectly... Greetings

[libvirt-users] questions around using numatune/numa/schedinfo
by Chris Friesen 26 Jan '15

26 Jan '15

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I initially hadn't had cgroups mounted and running "virsh schedinfo <domain>" gave an error. So I mounted "/sys/fs/cgroup/memory" and "/sys/fs/cgroup/cpu" and restarted libvirtd but running "virsh schedinfo <domain>" still gives an error: root@compute-1:~# virsh schedinfo 8 Scheduler : Unknown error: Requested operation is not valid: cgroup CPU controller is not mounted What am I missing? Thanks, Chris
