Yes. A signal is sent, and KVM returns from the guest to userspace on

is there a description available how this process exactly works?

The kernel part is in vcpu_enter_guest(), see the check for
signal_pending().  But this hasn't seen changes for quite a long while.

Thank you, i will have a look. I noticed a few patches that where submitted

during the last year, maybe one of them is related:

Switch SIG_IPI to SIGUSR1

Fix signal handling of SIG_IPI when io-thread is enabled

In the first commit there is mentioned a "32-on-64-bit Linux kernel bug"

is there any reference to that?

Thank you,

Peter
