Xen integration?
What is the reasoning behind disabling xen integration? I'm tempted to open a bug for the missing xen integration, but I assume there is a reason it is excluded. TripleSpeeder (talk) 14:43, 27 November 2012 (UTC)
libvirt-guests and systemd
libvirt-guests does not work with systemd. At least not without modification to the scripts. To enable a guest to auto-start you can either check the "autostart" box in virt-manager, enable autostart through virsh or you can manually create a symlink in the libvirt auto-start directory.
To automatically start a guest named www that runs in qemu
ln -s /etc/libvirt/qemu/www.xml /etc/libvirt/qemu/autostart/www.xml

virt-manager 0.9.4 broken?
virt-manager-0.9.4-4 python scripts don't seem to be working. I have been testing them all day.. Including but not limited to a full clean reinstall of Arch 4 times.. I have been getting the error: Building default storage pool failed error. So as a work around I used is below.. This is after the directories are created and root has access to them.
# virsh # pool-destroy default # pool-undefine default # pool-define-as --name default --type dir --target /path/to/default/directory # pool-autostart default # pool-build default # pool-start default # pool-destroy local # pool-undefine local # pool-define-as --name local-iso --type dir --target /path/to/default/local-iso/directory # pool-autostart local-iso # pool-build local-iso # pool-start local-iso # quit $ virt-manager

QEMU/libvirt broke
Last version broke for me. It was a permissions issue that i solved by creating a service account. I am running v1.0.2-1 with qemu.
Create service account for qemu:
# useradd -g kvm -M -N -r qemu
Edit to run under creds: /etc/libvirt/qemu.conf
user='qemu' group='kvm'
Also you will need to modify the permissions to the /dev/kvm
# chown root:kvm /dev/kvm

KVM acceleration after removing qemu-kvm package
In order to have KVM acceleration after the removal of qemu-kvm I had to edit the config of my virtual machines like this:
<domain type='qemu' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
<qemu:commandline>
<qemu:arg value='-machine'/>
<qemu:arg value='accel=kvm'/>
<qemu:arg value='kernel_irqchip=on' />
</qemu:commandline>
</domain>
I don't know if there is some specific field in libvirt XML, but this works for me.

bridged network edit
note: sorry this is typed all lowercase (broken wrist)
im looking to do an edit on bridged networking section im looking for a suggestion as what to keep since netcfg is deprecated...
i pretty much want to layout how to set a bridge with netctl...
Host
first find your network device to bridge...
ip a
it should be somthing along the lines of enpXXX
next create the bridge profile for netctl, then start and enable it
/etc/netctl/br0
Description="Internet bridge" Interface=br0 Connection=bridge BindsToInterfaces=(enp8s) IP=dhcp
netctl start br0
netctl enable br0
Guest
now this is where i need suggestions...is the current info relevant?
all i did was setup my vm to use br0 in virt-manager
i will go through these steps i used virt-manager but dont want to delete info if it isnt deprecate
- (Sorry for your wrist)
- Please don't delete anything if you're not sure of what you're doing: add templates like Template:Accuracy or Template:Out of date where appropriate instead. -- Kynikos (talk) 13:35, 16 July 2013 (UTC)
