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 Yanhui Ma 2015-07-30 05:19:31 UTC 
Description of problem:
After migrating RHEL7.2 guest with virtio-1 enabled virtio-scsi disk, run "fdisk -l", no output and the process status is D+.

If  w/o virito-1 enabled, can not hit such issue.

Version-Release number of selected component (if applicable):

source host:
3.10.0-297.el7.x86_64
qemu-kvm-rhev-2.3.0-13.el7.x86_64
destination host:
3.10.0-300.el7.x86_64
qemu-kvm-rhev-2.3.0-13.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot a RHEL7.2 guest with virtio-1 enabled virtio-scsi disk in src host

2.boot guest with listenning mode in destination host
3. migrate to destination host
4.after migrate, run "fdisk -l" & "ps aux | grep fdisk" in guest

Actual results:

after "fdisk -l", no output, after "ps aux | grep fdisk" the process status is D+.
ps aux | grep fdisk
root      3109  0.0  0.0 112420   956 pts/0    D+   11:16   0:00 fdisk -l
root      3836  0.0  0.0 112640   928 pts/1    S+   12:24   0:00 grep --color=auto fdisk

Expected results:
run "fdisk -l" successfully
Additional info:

If  w/o virito-1 enabled, can not hit such issue.
