What was the load on the system at the time?
Joshua pointed out that RCU stalls are common and there is a qemu option to extend the RCU stall maximum.
This log is odd, can you explain it:
qemu-system-x86_64: warning: TCG doesn't support requested feature: \
CPUID.01H:ECX.tsc-deadline [bit]
This looks like it's a mismatch between your AMD host and the intel vm.
Runqemu was recently changed to enable KVM by default.
Try turning off KVM:
qemu_use_kvm is the variable.
