Subject: qmeventd: VMID from PID: don't fail immediately when encountering unexpected entry
X-Git-Url: https://git.proxmox.com/?p=qemu-server.git;a=commitdiff_plain;h=aaa77c9f7aa4419139a86f397abc4fce8a8e76dd

qmeventd: VMID from PID: don't fail immediately when encountering unexpected entry

While such entries shuoldn't exist in practice without manually
messing around, it's not hard to imagine, and there's still a good
chance the actual VMID can still be found.

It's still unexpected to encounter such entries so keep the log line.
