[libvirt] virt-install ERROR Host does not support any virtualization options
Hello, I face this problem and I am willing to provide a patch in order to have a more informative message. This, of course with our help. I am not quite certain. First of all: What is the problem? On a fresh Install (ArchLinux for me), if ever forget to install Qemu and launch "virt-install" with "--type kvm", I get the message: "Host does not support any virtualization options" According to me, this message should be improved: if Qemu is not found, this should be "Did not find Qemu, please install it". As I searched, the message is generated by this piece of code: https://github.com/virt-manager/virt-manager/blob/c92aade081687b19f5a60cddfe331b2fb6d09f98/virtinst/capabilities.py#L390 As I write now, I cant find the pice of code actually calling the "quemu" binary. I think I should add a try/catch block there and Raise the right Exception. Would someone help me a bit? Thank you. -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

[libvirt] KVM Windows guest: add hard drive
Manao ahoana, Hello, Bonjour, I installed a Windows (XP and 2003) guest using one partition as hard drive. I used: sudo virt-install --connect qemu:///system \ --name win2003-01 \ --ram 1024 \ --keymap=fr \ --disk path=/dev/lvm0/win2003-01 \ --cdrom=/home/mihamina/Windows_2003_Server.iso \ --os-type windows \ --os-variant=win2k3 \ --noapic \ --noacpi \ --network=bridge:br0 \ --accelerate \ --vnc \ --force And this works fine. Really fine. The disk section in the definition: disk type='block' device='disk' source dev='/dev/lvm0/win2003-01'/ target dev='hda' bus='ide'/ /disk After installation, people asked me to add another hard drive to this installation, and then, I added another disk in the definition: disk type='block' device='disk' source dev='/dev/lvm0/win2003-01'/ target dev='hda' bus='ide'/ /disk disk type='block' device='disk' source dev='/dev/lvm0/win2003-01-a'/ target dev='hdb' bus='ide'/ /disk I destroyed + undefined + defined + started the VM and the definition is OK (dumpxml), but the Windows guest doesnt see any new hard drive. I already tried with replacing ide with virtio, no new hard drive yet.

[libvirt] cpulimit and kvm process
Manao ahoana, Hello, Bonjour, I would like to launch several KVM guests on a multicore CPU. The number of the KVM process is over the number of physical cores. I would like to limit each KVM process to say... 10% of CPU I first use cpulimit Would you know some better way to limit them? it's in order to avoid 4 VM to hog all the 4 hardware cores.

[libvirt] command line chroot in a VM
Manao ahoana, Hello, Bonjour,
From the host, I would like to perform a batch operation on the guests.
For example:
# virsh list
1 001
2 002
3 003
All guests are KVM, Debian Lenny
I want to
for GUEST in $(virsh list | awk '{blah blah}')
do
? ${GUEST} apt-get update
? ${GUEST} apt-get upgrade
done
And then I just have to *read* and answer yes or no to the apt
questions.
The host is a Debian Lenny, but I can backport some packages if needed.
What would be your suggestions?
- libguestfs? (I see an unstable debian package existing)
- ...?
Misaotra, Thanks, Merci.

[libvirt] DNAT, bridge, iptables and network
Manao ahoana, Hello, Bonjour, My server has 3 public IPs: IP1, IP2, IP3. I intend to create 3 bridges: virbr1, virbr2, virbr3. Each bridge will NAT from 3 to 5 KVM guests. About IP1: I would like incoming connexion on IP1 to: - IP1:80 to be DNAT'd to one virbr1 VM, specialized on HTTP - IP1:3306 to be DNAT'd to another virbr1 VM, specialized on MySQL - IP1:53 to be DNAT'd to another virbr1 VM, specialized on DNS Same about IP2 and IP3. Should I assign a public IP address to each brdige? I think no because there will be a problem of network segment: -- What range will I give to the guests? I think my only solution is to give private IPs (192.168.X.X) to the brigdes (3 separate subnets), and use iptables with something like: iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 80 \ -j DNAT --to-destination $VIRBR1_HTTP_GUEST iptables -t nat -A PREROUTING -p tcp -m tcp -d $IP1 --dport 3306 \ -j DNAT --to-destination $VIRBR1_MySQL_GUEST iptables -t nat -A PREROUTING -p udp -d $IP1 --dport 53 \ -j DNAT --to-destination $VIRBR1_DNS_GUEST Should be alright?

Re: [libvirt] Libvir on Hardy: file a bug or not?
Daniel P. Berrange wrote: The Ubuntu libvirt had a early version of the patch for supporting the 'boot=on' parameter - I believe they always use it for any VM with a domain type of 'kvm'. Since you are using regular QEMU it is correct that you need to change the domain type to type=qemu anyway. My problem if I use qemu as domain type is the guest is slow enough to make me think it doesnt use the kvm. In the beginning, and in Ubuntu documentation, the domain type is qemu as default. So, the question that might solve the problems: How can assume it's realy using kvm (and not just qemu)? Note: when I launch the guest via the kvm command [1], it's faster.

If I change the domain type with qemu, I have no error (and the

qemu 0.9.1-1ubuntu1

Is it an upstream bug or a distribution bug?
Who is supposed to be noticed? The packager or the upstream (where please)?
