Do I need to restart after dom0 update?

Hi

After I update dom0 there’s no any messages indicating I need to restart the system as on other OSes. How do I know if I need to perform a restart or not?

Depends on what was updated. You definitely need to restart to apply changes after “kernel” and/or “xen” updates, and in certain cases, for libc/glibc. After other updates you don’t need to restart.

How can I tell if it was xen or kernel?

By looking at the terminal output in the Qubes update tool

Yes but what should I look for? For kernel I should see something with “kernel” explicitly, what about xen?

Literally… “xen” or “xen-something” (xen-hvm, xen-hypervisor and so on). :slight_smile:

These are the xen packages installed in R4.3.0:

user@dom0:~$ rpm -qa | grep xen
