| H A D | vmm.h | diff 265101 Tue Apr 29 16:49:10 MDT 2014 neel Some Linux guests will implement a 'halt' by disabling the APIC and executing the 'HLT' instruction. This condition was detected by 'vm_handle_hlt()' and converted into the SPINDOWN_CPU exitcode . The bhyve(8) process would exit the vcpu thread in response to a SPINDOWN_CPU and when the last vcpu was spun down it would reset the virtual machine via vm_suspend(VM_SUSPEND_RESET). This functionality was broken in r263780 in a way that made it impossible to kill the bhyve(8) process because it would loop forever in vm_handle_suspend(). Unbreak this by removing the code to spindown vcpus. Thus a 'halt' from a Linux guest will appear to be hung but this is consistent with the behavior on bare metal. The guest can be rebooted by using the bhyvectl options '--force-reset' or '--force-poweroff'. Reviewed by: grehan@ |
