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 Richard W.M. Jones 2015-06-08 15:02:31 UTC

Description of problem:

After conversion using the automated kernel command line mode, virt-p2v
really ought to power off the machine.

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

virt-p2v from git, or RHEL 7.1

How reproducible:

100%

Steps to Reproduce:

Please see my reproducer steps here:
https://bugzilla.redhat.com/show_bug.cgi?id=1229262#c2

Actual results:

virt-p2v runs invisibly (or fails invisibly), and there's no obvious
conclusion to the conversion, unless you study the log files on the
conversion server.

Expected results:

virt-p2v should power off the server after completion.

Comment 2 Richard W.M. Jones 2015-06-09 19:24:46 UTC

Upstream fixes:

716244c33718c866edce9e7ee8f21ee612f53337
b45f6a04359b4b64256b7b21a04416fa772c9423

These fixes actually add various commands you can use to
run scripts before and after conversion:

       p2v.pre=COMMAND
       p2v.pre="COMMAND ARG ..."
           Select a pre-conversion command to run.  Any command or script can
           be specified here.  If the command contains spaces, you must quote
           the whole command with double quotes.  The default is not to run
           any command.

       p2v.post=poweroff
       p2v.post=reboot
       p2v.post=COMMAND
       p2v.post="COMMAND ARG ..."
           Select a post-conversion command to run if conversion is
           successful.  This can be any command or script.  If the command
           contains spaces, you must quote the whole command with double
           quotes.

           If virt-p2v is running as root, and the command line was set from
           "/proc/cmdline" (not --cmdline), then the default is to run the
           poweroff(8) command.  Otherwise the default is not to run any
           command.

       p2v.fail=COMMAND
       p2v.fail="COMMAND ARG ..."
           Select a post-conversion command to run if conversion fails.  Any
           command or script can be specified here.  If the command contains
           spaces, you must quote the whole command with double quotes.  The
           default is not to run any command.

Comment 4 tingting zheng 2015-06-11 03:29:13 UTC

Tested with:
livecd-p2v-201506091319.iso
virt-v2v-1.28.1-1.38.el7.x86_64
libguestfs-1.28.1-1.38.el7.x86_64

1.Check virt-p2v manual:
# man virt-p2v,the part about p2v.pre,p2v.post have been added.
p2v.pre=COMMAND
p2v.pre="COMMAND ARG ..."
Select a pre-conversion command to run. Any command or script can be specified here. If the
command contains spaces, you must quote the whole command with double quotes. The default is not to
run any command.

p2v.post=poweroff
p2v.post=reboot
p2v.post=COMMAND
p2v.post="COMMAND ARG ..."
Select a post-conversion command to run if conversion is successful. This can be any command or
script. If the command contains spaces, you must quote the whole command with double quotes.

If virt-p2v is running as root, and the command line was set from "/proc/cmdline" (not --cmdline),
then the default is to run the poweroff(8) command. Otherwise the default is not to run any
command.

p2v.fail=COMMAND
p2v.fail="COMMAND ARG ..."
Select a post-conversion command to run if conversion fails. Any command or script can be specified
here. If the command contains spaces, you must quote the whole command with double quotes. The
default is not to run any command.

2.Use virt-p2v to convert host.
For default(didn't set anything about p2v.post) in kernel command line,it will poweroff after conversion.

If set p2v.fail=reboot or p2v.post=reboot,If the conversion fail or finish,the host will reboot.

Refer to the above comments,move the bug to VERIFIED.
