I have some VM on qemu, which occasionally freezes.
Thus I need some way to send sysrq to my VM. I use both TigerVNC and picocom, but the appropriate hotkeys (e.g. Alt + PrtScr + B) don't work. Obviously, in this case Alt + PrtScr + B sends sysrq to my host Linux, not VM.
So is there a way to send sysrq to VM through the picocom terminal or TigerVNC?
Seem that it's related to somehow sending "break" in case of picocom.
