[libvirt-users] Cannot migrate vm between servers
by Chris Lewis 15 Jul '15

15 Jul '15

Hello, I issue the command below to migrate virtual machine "jabber" from host vmserver5 to vmserver3 I see the machine is created at the destination, paused on both sides, but the process fails with the error below (and the destination VM is removed) root@vmserver5:~/# virsh migrate --p2p --unsafe jabber qemu+ssh://vmserver3/system error: internal error: migration was active, but no RAM info was set Relevant Software versions: vmserver5: ||/ Name Version Architecture Description +++-==============================================-============================-============================-= vmserver3: ||/ Name Version Architecture Description +++-==================================-=============================-============-============================ ii kvm 1:1.1.2+dfsg-6+deb7u8 amd64 dummy transitional package from kvm to qemu-kvm ii libvirt-bin 1.2.9-9~bpo70+1 amd64 programs for the libvirt library ii qemu-kvm 1.1.2+dfsg-6+deb7u8 amd64 Full virtualization on x86 hardware Both machines have shared storage mounted in same place. Very little info on web regarding this error. Can anyone suggest what is going on? Thanks in advance Chris Lewis

[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] How to enable vmx (virtual machine extensions) in virt-manager
by KARR, DAVID 15 Jul '15

15 Jul '15

I need to enable virtual machine extensions, like as described at http://www.server-world.info/en/note?os=Ubuntu_14.04&p=kvm&f=8 . I could do this in virsh, but I'd like to know if it's possible to do in virt-manager. I don't see an obvious way to do that.

[libvirt-users] Debug VM boot from ISO issues
by KARR, DAVID 15 Jul '15

15 Jul '15

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? Yup. > I'll check those vendor IDs above. > > How can I check the ones what Qemu using? (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

[libvirt-users] Migrate Win2k3 to KVM
by Ruzsinszky Attila 12 Jul '15

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

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.
