Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

How reproducible:
always

Steps to Reproduce:
1./usr/libexec/qemu-kvm  -M rhel5.6.0 -m 4096 -smp 4,cores=2,threads=1,sockets=2 -cpu qemu64,vendor="AuthenticAMD",+sse2 -soundhw all -name win7 -usbdevice tablet -rtc-td-hack -uuid 123465d2-2032-848d-bda0-de7adb149048 -boot c -drive file=/home/rhel6.2.z-64.qcow2,if=virtio,boot=on,bus=0,unit=0,format=qcow2,cache=none,boot=on,werror=stop -net nic,macaddr=54:52:00:27:12:23,vlan=0,model=virtio -net tap,vlan=0,script=/etc/qemu-ifup -serial pty -parallel none -usb -balloon none -monitor stdio -vnc :1,password

2.change vnc password
(qemu) change vnc password
Password:123456

3.boot des guest
/usr/libexec/qemu-kvm  -M rhel5.6.0 -m 4096 -smp 4,cores=2,threads=1,sockets=2 -cpu qemu64,vendor="AuthenticAMD",+sse2 -soundhw all -name win7 -usbdevice tablet -rtc-td-hack -uuid 123465d2-2032-848d-bda0-de7adb149048 -boot c -drive file=/home/rhel6.2.z-64.qcow2,if=virtio,boot=on,bus=0,unit=0,format=qcow2,cache=none,boot=on,werror=stop -net nic,macaddr=54:52:00:27:12:23,vlan=0,model=virtio -net tap,vlan=0,script=/etc/qemu-ifup -serial pty -parallel none -usb -balloon none -monitor stdio -vnc :1,password -incoming tcp:0:5555

4.migrate
(qemu) migrate -d tcp:10.66.9.97:5555

5.use vncview and password(123456) to connect des guest 
  vncviewer 10.66.9.97:5901

Comment 1 Gerd Hoffmann 2011-12-12 09:53:51 UTC 
Why is this an issue?  The management stack (libvirt / virt-manager / rehvm) should take care to set the password on the migration target, no?

I'll go close with WOUNTFIX unless someone can come up with a good reason why this is needed.
Comment 2 Gerd Hoffmann 2012-01-04 12:01:19 UTC 
no news -> close (see comment 1).
