Retest this issue with kernel: 3.10.0-61.el7.x86_64 and qemu_kvm: qemu-kvm-1.5.3-30.el7.x86_64 Steps: 1. Boot up a RHEL7.0 guest in source host and listening with "incoming" in des host: 2. Migrate from src host to des host: 3. After migration, inside guest run "halt -p", can shutdown the guest. Given that the original report says 100% reproduce rate and both attempts to reproduce (comments 4+5) failed, with more recent versions than the original report, I suspect this one is simply fixed meanwhile. Should it show up again please reopen the bug. |
Description of problem: After migration, run "halt -p" inside the guest, guest can't be shutdowned. Even 10 minites later, guest can not be shutdowned yet. Version-Release number of selected component (if applicable): qemu-kvm-1.5.2-2.el7.x86_64 3.10.0-4.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Boot two RHEL7.0 guests on two hosts and do migration. 2.After migration, run "halt -p" command inside guest 3. Actual results: guest console output: # nc -U /tmp/ttyS0 [root@localhost ~]# [ 223.549400] systemd[1]: bus_connection_get_unix_fd failed Broken pipe [ 233.842033] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 5 6 7} (detected by 0, t=60002 jiffies, g=831, c=830, q=22782) [ 346.959056] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 5 6 7} (detected by 0, t=60002 jiffies, g=848, c=847, q=12051) [ 423.757055] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 4 5 6 7} (detected by 0, t=60002 jiffies, g=855, c=854, q=12021) [ 487.746056] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 4 5 6 7} (detected by 2, t=60003 jiffies, g=857, c=856, q=12021) [ 551.734058] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 4 5 6 7} (detected by 2, t=60003 jiffies, g=860, c=859, q=12337) [ 622.142055] INFO: rcu_sched detected stalls on CPUs/tasks: { 1 3 4 5 6 7} (detected by 0, t=60002 jiffies, g=864, c=863, q=12337) ---------------------------- qeu-kvm process status: # ps -ef |grep qemu-kvm # top -p 21400 top - 11:45:23 up 2 days, 1:30, 5 users, load average: 0.01, 0.04, 0.05 Tasks: 1 total, 0 running, 1 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.0 us, 0.0 sy, 0.0 ni, 99.6 id, 0.2 wa, 0.2 hi, 0.0 si, 0.0 st KiB Mem: 7594624 total, 3856348 used, 3738276 free, 86636 buffers KiB Swap: 8142844 total, 173196 used, 7969648 free, 2604348 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 21400 root 20 0 5788964 533136 7996 S 8.988 7.020 1:15.61 qemu-kvm --------------------------------- # kvm_stat kvm statistics kvm_exit 31422 2033 kvm_entry 31422 2033 kvm_msr 15420 1006 kvm_inj_virq 15325 1006 kvm_eoi 15324 1006 kvm_apic_accept_irq 15324 1006 kvm_pv_eoi 15200 1004 kvm_fpu 258 16 kvm_pio 249 12 kvm_userspace_exit 249 12 kvm_emulate_insn 191 9 kvm_set_irq 67 3 kvm_pic_set_irq 67 3 kvm_ioapic_set_irq 67 3 kvm_msi_set_irq 31 2 kvm_apic 126 1 kvm_ack_irq 16 1 kvm_exit(HLT) 33 0 kvm_exit(MSR_WRITE) 33 0 kvm_exit(EXCEPTION_NMI) 1 0 Expected results: After migration, guest can be shutdowned as normal.
