Cannot 'standby' guest RHEL5.5
Last modified: 2013-12-08 19:45:33 EST
Description of problem:
Found there is no 'standby' in '/sys/power/state'. Cannot guest RHEL-5.5 detect ACPI 'standby' or it doesn't support at all? Tested this on real HW installed RHEL-Server-5.5, worked fine.
Version-Release number of selected component (if applicable):
Guest kernel: 2.6.18-182.el5
Steps to Reproduce:
1. Start guest: #/root/autotest/client/tests/kvm/qemu -name 'vm1' -monitor tcp:0:6001,server,nowait -drive file=/root/autotest/client/tests/kvm/images/RHEL-Server-5.4-32.qcow2,if=ide,boot=on -net nic,vlan=0,model=e1000,macaddr=00:AE:9D:90:9C:00 -net tap,vlan=0,ifname=e1000_0_6001,script=/root/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 512 -smp 1 -usbdevice tablet -rtc-td-hack -no-hpet -cpu qemu64,+sse2 -no-kvm-pit-reinjection -vnc :0
2. entered into guest, issue command: #cat /sys/power/state
(or issue: #echo standby > /sys/power/state
3. cannot find 'standby' in power-state file (cannot standby guest)
Cannot find 'standby'
Can standby guest like host which is 5.5 as well
We do not support "standby" (S1) in kvm. The only states that are supported: "mem" (S3) and "disk" (S4). And S3 is only supported for windows WHQL testing so after entering this state kmv immediately resumes. Closing the bug.
