Where is the xml file for the kvm stored?

They are stored inside the libvirt.img file that is mounted at /etc/libvirt.

 

When mounted the full path to the where they are stored is /etc/libvirt/qemu

Thanks.

 

Is it a way to backup and restore individual xml`s for specific kvm`s?

 

@frodr I use the following user script running once a day someone posted here on the forum. Can't find the source right now. It saves the xml and the NVRAM files in a zip file in the path you have to set at the top. Backups older than 30 days gets cleaned out with every run.

 

#!/bin/bash
#backs up
#change the location below to your backup location 
backuplocation="/mnt/user/Backup/vm_settings/"

# do not alter below this line
timestamp=`date '+%Y-%m-%d__%H-%M-%S'`
dir="$backuplocation"vm_settings/"$timestamp"
# dont change anything below here
if [ ! -d $dir ] ; then
 
			echo "making folder for todays date $timestamp"

			# make the directory as it doesnt exist
			mkdir -vp $dir
		else
			echo "As $dir exists continuing."
			fi

echo "Saving vm xml files"
rsync -a --no-o /etc/libvirt/qemu/*xml $dir/xml/
echo "Saving ovmf nvram"
rsync -a --no-o /etc/libvirt/qemu/nvram/* $dir/nvram/
chmod -R 777 $dir

		echo "information: creating ZIP-archive and cleaning up old data"
    zip -r -9 "$backuplocation"vm_settings/"$timestamp".zip "$backuplocation"vm_settings/"$timestamp" && rm -r "$backuplocation"vm_settings/"$timestamp"
