I'm exporting a domain from 'old pc' to 'new pc'

# Export domain (from old pc)
ssh user@"$REMOTE_IP" "virsh --connect qemu:///system suspend --domain magento-base > /dev/null 2>&1"                                                                                       # Pause vm
ssh user@"$REMOTE_IP" "virsh --connect qemu:///system dumpxml --update-cpu --domain magento-base > ~/workspaces/virtual-machines/magento-base/magento-base.xml"                             # Export vm
ssh user@"$REMOTE_IP" "virsh --connect qemu:///system snapshot-dumpxml --domain magento-base --snapshotname snapshot1 > ~/workspaces/virtual-machines/magento-base/snapshots/snapshot1.xml" # Export snapshot1

# Import domain (to new pc)
virsh --connect qemu:///system destroy --domain magento-base > /dev/null 2>&1                                                                                                          # Stop old vm
virsh --connect qemu:///system undefine --domain magento-base > /dev/null 2>&1                                                                                                         # Delete old vm
virsh --connect qemu:///system define ~/workspaces/virtual-machines/magento-base/magento-base.xml                                                                                      # Import new vm
virsh --connect qemu:///system snapshot-create --domain magento-base --xmlfile ~/workspaces/virtual-machines/magento-base/snapshots/snapshot1.xml --atomic --redefine --current --halt # Import snapshot1

PROBLEM When I start the domain, or the snapshot in the new pc, I get the error:

The CPU is incompatible with host CPU

What's the right way to fix this error? Thank you.

That's when I run the command 'virt-install'

virt-install --connect=qemu:///system --name=mymachine --ram=4096 --vcpus=2 --check-cpu --os-type=ubuntu --vnc --accelerate --disk=/home/myuser/mymachine/mymachine.qcow2,sparse=true --network=bridge:br0

Things I've already checked out:

  • kvm modprobe is running (checked with lsmod | grep kvm )
  • Virtualization is enabled on my bios
  • The flag --hvm

More info:

  • Hardware: HP laptop with Intel CPU I5
  • OS: Manjaro 20.04 (arch)
  • Package: libvirt from community

Virtualbox runs fine so I'm a bit puzzled here. Also, on my other computer the command runs correctly. Any idea about what could be going on?

Hi I'm try to do an installer which is compatible among different linux distros. It is possible to achieve something like this (see the last line of code).

PACKAGE_MANAGER=$1
INSTALL_PACKAGE_CMD=""

# CHECK PACKAGE MANAGER
if [ "$s1" == apt ]
then INSTALL_PACKAGE_CMD="apt install -y" fi
if [ "$s1" == pacman ]
then INSTALL_PACKAGE_CMD="pacman --noconfirm --force" fi

# INSTALL PACKAGE 
# (using the selected package manager)
sudo $INSTALL_PACKAGE_CMD sqlite
