On a POWER9/PowerNV host, when running a pSeries guest using QEMU, sporadic interrupt timing warnings are observed. This is on kernel 6.12 (Debian Stable) on both host and guest, system load is moderate, the host CPUs are not pegged at 100% at any time. The guest has only one virtual CPU core assigned.
[11622.031047] hrtimer: interrupt took 12354614 ns [46723.139964] hrtimer: interrupt took 8522695 ns This *may* be related to the dropped / late interrupts I have reported in earlier messages, but it could also be a separate issue. QEMU version is 7.2.22.
