This is highly unlikely have anything to do with kvm or qemu (unless the same image works in rhel6). Reinstall the guest and try again. (In reply to comment #4) > Can you include kvm_stat data ?

Created attachment 497945 [details] boot time(appended single) Description of problem: 1.boot guest with single mode,guest stuck. 2.after fully startup,type "init 1" in guest,guest stuck. Version-Release number of selected component (if applicable): kvm-83-232.el5 How reproducible: always Steps to Reproduce: 1.boot a rhel5.6-64 guest qemu-kvm -name rhel -monitor stdio -serial unix:/t..,server,nowait \ -drive file=5.6-64.qcow2,index=0,if=ide,media=disk,cache=none,format=qcow2 \ -net nic,vlan=0,model=rtl8139,macaddr=52:54:00:12:34:56 \ -net tap,vlan=0,ifname=rhel56-64,script=ifup-switch,downscript=no \ -m 2048 -smp 2,cores=2,threads=1,sockets=1 \ -cpu qemu64,+sse2 -soundhw ac97 -vnc :10 \ -rtc-td-hack -M rhel5.6.0 -boot c -usbdevice tablet 2. edit grub option during boot time, append "single" to the end of kernel line. 3. Actual results: guest stucks during boot ,pls see snapshot Expected results: guest boot normally Additional info: host info kernel-2.6.18-260.el5 CPU INFO processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E5310 @ 1.60GHz stepping : 11 cpu MHz : 1595.925 cache size : 4096 KB 32G RAM top info (show threads) Tasks: 5 total, 0 running, 5 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 32940096k total, 1286896k used, 31653200k free, 43556k buffers Swap: 34996216k total, 0k used, 34996216k free, 386600k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4674 root 15 0 2327m 703m 2536 S 0.0 2.2 0:08.93 qemu-kvm 4683 root 15 0 2327m 703m 2536 S 0.0 2.2 0:00.73 qemu-kvm 4684 root 15 0 2327m 703m 2536 S 0.0 2.2 5:51.64 qemu-kvm 4685 root 16 0 2327m 703m 2536 S 0.0 2.2 2:25.33 qemu-kvm 4686 root 15 0 2327m 703m 2536 S 0.0 2.2 0:00.00 qemu-kvm guest info: kernel-2.6.18-260.el5 grub kernel options kernel /vmlinuz-2.6.18-260.el5 ro root=/dev/VolGroup00/LogVol00 console=ttyS0,115200 console=tty0 single
