This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. Which version of the virtio-serial driver is used? (In reply to Gal Hammer from comment #10) > Which version of the virtio-serial driver is used? Gal, I can not rem which version of the virtio-serial driver was used at that time, so I re-test again with the latest virtio-serial in virtio-win-prewhql-72. And the problem still exist. Host version: [root@localhost ~]# uname -r 2.6.32-422.el6.x86_64 [root@localhost ~]# rpm -q qemu-kvm qemu-kvm-0.12.1.2-2.411.el6.x86_64 Guest: (1) virtio-serial: From virtio-win-prewhql-72 (2) qemu-ga: Use the qemu-ga.exe extracted from qemu-kvm-389 because can not use the latest qemu-ga Yan provided in bug 971141.

Moving this bug from RHEL6.6 to RHEL7.0 in order to comply with our current process (everything is RHEL7). It is a virtio-win bug fix, that will be included in the RHEL7 package, so it needs the blocker+ flag.

Description of problem: Install windows guest agent and start the service and then implement S3 or S3, the guest agent is not available any more. No response after send command to guest agent. I have to restart the qemu-ga service to make it work again. Tried RHEL guest, this issue does not exist. Version-Release number of selected component (if applicable): Host: kernel-2.6.32-348.el6.x86_64 qemu-kvm-0.12.1.2-2.346.el6.x86_64 Guest: Win7-32 and win2012, installed the executable from qemu-guest-agent-win32-0.12.1.2-2.346.el6.x86_64 How reproducible: Always Steps to Reproduce: 1. Boot a guest /usr/libexec/qemu-kvm -M rhel6.4.0 -enable-kvm -m 2048 -smp 2,sockets=2,cores=1,threads=1 -enable-kvm -name t2-rhel6.4-32 -uuid 61b6c504-5a8b-4fe1-8347-6c929b750dde -k en-us -rtc base=localtime,clock=host,driftfix=slew -no-kvm-pit-reinjection -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device usb-tablet,id=input0 -drive file=/home/win7-32.qcow2,if=none,id=disk0,format=qcow2,werror=stop,rerror=stop,aio=native -device ide-drive,bus=ide.0,unit=1,drive=disk0,id=disk0 -drive file=/home/en_windows_7_ultimate_with_sp1_x86_dvd_619077.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,drive=drive-ide0-1-0,bus=ide.1,unit=0,id=cdrom -netdev tap,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=44:37:E6:5E:91:85,bus=pci.0,addr=0x5 -monitor stdio -qmp tcp:0:6666,server,nowait -chardev socket,path=/tmp/isa-serial,server,nowait,id=isa1 -device isa-serial,chardev=isa1,id=isa-serial1 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x8 -chardev socket,id=charchannel0,path=/tmp/serial-socket,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.rhevm.vdsm -chardev socket,path=/tmp/foo,server,nowait,id=foo -device virtconsole,chardev=foo,id=console0 -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x9 -spice port=5930,disable-ticketing -vga qxl -global qxl-vga.vram_size=67108864 -k en-us -boot c -chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 -device virtserialport,bus=virtio-serial0.0,chardev=qga0,name=org.qemu.guest_agent.0 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 2. Install the qemu-guest-agent-win32-0.12.1.2-2.346.el6.x86_64 on a rhel host and get the executable. 3. Install the qemu-ga.exe inside windows guest. #c:\qemu-ga>qemu-ga.exe --service install 4. In guest: In guest, open "services.msc" and check if qemu-ga service is started. If not, start the qemu-ga service. 5. Suspend guest to mem or disk. # nc -U /tmp/qga.sock { "execute": "guest-ping"} {"return": {}} { "execute": "guest-sync-delimited", "arguments": { "id": 123456 } } �{"return": 123456} { "execute": "guest-suspend-ram" } or { "execute": "guest-suspend-disk" } 6. After guest resume, send command to guest agent again. # nc -U /tmp/qga.sock { "execute": "guest-ping"} { "execute": "guest-sync-delimited", "arguments": { "id": 123456 } } Actual results: After step 6, no response. Need to restart qemu-ga service inside guest to make sure the guest agent works again. Expected results: After step 6, guest agent should still work. Additional info: If disable guest agent and start qemu-ga.exe manually, after resume from guest, there's some error print out. In the meanwhile, guest agent has no response after send some command to it. Need to interrupt the qemu-ga.exe and re-start again. c:\qemu-ga>qemu-ga.exe -m virtio-serial 1355965843.421875: critical: channel error, removing source
