RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Golita Yue 2010-05-06 08:08:52 UTC 
Description of problem:
The guest was hang and could not click it in VNC-window after Migration via a compressed file. Ping was failed yet.

Version-Release number of selected component (if applicable):
HOST:
kernel-2.6.32-23.el6.x86_64
qemu-kvm-0.12.1.2-2.48.el6.x86_64

GUEST:
I tried r5u5_64b, r6u-server-32b, win7-32b, all failed

How reproducible:
4/4

Steps to Reproduce:
1. start guest
cmd:/usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -startdate now -cpu qemu64,+sse2 -drive file=/home/r5u5_64-back.raw,if=ide,boot=on -net nic,model=rtl8139,macaddr=20:20:11:23:22:00,vlan=0 -net tap,script=/etc/qemu-ifup,downscript=no,vlan=0 -vnc :1 -m 2G -smp 1 -balloon none -boot c -monitor stdio -uuid `uuidgen` -no-kvm-pit-reinjection
2. run Migration via a compressed file
(qemu) stop
(qemu) migrate "exec:gzip -c > STATEFILE.gz"
3. start listening mode
cmd:/usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -startdate now -cpu qemu64,+sse2 -drive file=/home/r5u5_64-back.raw,if=ide,boot=on -net nic,model=rtl8139,macaddr=20:20:11:23:22:00,vlan=0 -net tap,script=/etc/qemu-ifup,downscript=no,vlan=0 -vnc :2 -m 2G -smp 1 -balloon none -boot c -monitor stdio -uuid `uuidgen` -no-kvm-pit-reinjection -incoming "exec: gzip -c -d STATEFILE.gz"

4. try to use mouse on guest vnc-window, could not click 
   no network(failed ping guest)
but,(qemu) info status
    VM status: running

  
Actual results:
guest was hung up

Expected results:
guest is running after migration via a compressed file

Can you retry w/o compression?
Comment 4 Mike Cao 2010-05-11 11:38:56 UTC

Windows 2008 r2,
Windows 7 32bit,
windows 7 64bit,

steps:
1.start the guest with :-smp 1
2.Do migration via compressed file.

actual results:
the guest was hung
inthe qemu monitor #info status
 VM status: running

additional info:
1.start the guest with:-smp 2
2.Do migration via compressed file.

the guest can work on well,will NOT hint the issue.

Migrate without compression:

1. start guest
/usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -startdate now -cpu qemu64,+sse2 -drive file=/mnt/r5u5_64.raw  -net nic,model=rtl8139,macaddr=20:20:11:23:21:01,vlan=0 -net tap,script=/etc/qemu-ifup,downscript=no,vlan=0 -vnc :1 -m 2G -smp 1 -balloon none -boot c -monitor stdio -uuid `uuidgen`
QEMU 0.12.1 monitor - type 'help' for more information
2. migrate
(qemu) stop
(qemu) migrate "exec: dd of=gyue-r5-migrate"
1029887+1 records in
1029887+1 records out
527302503 bytes (527 MB) copied, 496.766 s, 1.1 MB/s
(qemu) 
(qemu) info migrate
Migration status: completed
(qemu) 
(qemu) quit
3. start guest in listening mode
 /usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -startdate now -cpu qemu64,+sse2 -drive file=/mnt/r5u5_64.raw  -net nic,model=rtl8139,macaddr=20:20:11:23:21:01,vlan=0 -net tap,script=/etc/qemu-ifup,downscript=no,vlan=0 -vnc :1 -m 2G -smp 1 -balloon none -boot c -monitor stdio -uuid `uuidgen` -incoming "exec: dd if=gyue-r5-migrate"

527302503 bytes (527 MB) copied, 2.56788 s, 205 MB/s
(qemu) info status
VM status: running

Result: I cannot use mouse and keyboard in guest, and the guest was hung look likely.
Comment 6 Juan Quintela 2010-06-29 11:04:31 UTC 
This works for me (tm).  Attached my configuration.  I tried with f13 linux console and rhel55 X install, both worked with keyboard and mouse.  Could you retry?

Which (qemu-kvm & kernel) version did you use?

Should I retry it in qemu-kvm-0.12.1.2-2.48.el6.x86_64 ? or the latest version ?
Comment 8 Juan Quintela 2010-06-30 13:04:44 UTC 
This ones work for me.


[root@deus ~]# rpm -qa kernel qemu-kvm
kernel-2.6.32-37.el6.x86_64
qemu-kvm-0.12.1.2-2.78.el6.x86_64

I try again with #commnet5 steps, cannot reproduce this bug in
qemu-kvm-0.12.1.2-2.82.el6.x86_64
kernel 2.6.32-38.el6.x86_64
