Dell Customer Communication Hi everyone, I am trying to do a virsh using TLS Certificate. I am getting an error that "error: authentication failed: Failed to verify peer's certificate" I am following the steps mentioned in the http://wiki.libvirt.org/page/TLSSetup I have generated CA Certificate, client certificate and server certificate and placed them as mentioned in above site. After that when I am trying to do a virsh it is failing. Please let me know if anyone has encountered this kind of issue. virsh -c qemu+tls://172.14.5.6/system list error: failed to connect to hypervisor error: authentication failed: Failed to verify peer's certificate Thanks & Regards, Dhaval Shah

[libvirt-users] Migrate KVM linux based VM to microsoft Hyper-v
by test comp 20 Jul '15

20 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

Hi, I need to set up a two -nodes RHEL cluster in order to check KVM guests migration stuff. Could you , please , give me some advice regarding : - HW pieces I need to setup the cluster ( I already got the two servers) - The RHEL packages and subscriptions needed for the cluster and the guests management on top of this cluster. Thx for help. J.P.

[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] 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 14 Jul '15

14 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 14 Jul '15

14 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 13 Jul '15

13 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
