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.

Screenshot of virt-p2v error under no GUI mode

Description:
virt-p2v no GUI mode:error opening control connection to $ip:22:unexpected …rompt

Version:
virt-p2v-1.28.1-1.49.1.el7
virt-v2v-1.28.1-1.49.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare pxe to boot virt-p2v client.Add virt-p2v options in the APPEND field in the pxelinux.cfg file.
eg:
APPEND rootflags=loop initrd=initrd0.img root=live:/virt-p2v-livecd-1.28.1-1.49.1.el7.iso p2v.server=10.66.4.243 p2v.password=redhat p2v.memory=1024M p2v.name=p2v-test-nogui p2v.vcpus=1 p2v.disks=sda p2v.removable=sr0 p2v.o=disk p2v.oa=sparse p2v.of=raw p2v.os=/var/tmp rootfstype=auto ro rd.live.image quiet console=tty0 console=ttyS0,115200 rd_NO_PLYMOUTH net.ifnames=0 rd.luks=0 rd.md=0 rd.dm=0 
2.Boot host from pxe.
3.Host boot into console mode with root shell directly,run the below command,there is an error info as below.
# journalctl -u p2v --follow 
virt-p2v:error opening control connection to $ip:22:unexpected …rompt
xinit:connection to X server lost.
Started p2v service.
4.Check logs in virt-p2v server(10.66.4.243),the conversion doesn't start,I need to run the below command and can start the service manually.
# launch-virt-p2v

Actual results：
As description:
Error shows:virt-p2v:error opening control connection to $ip:22:unexpected …rompt
The error info shows is quite misleading,which users may think there is something wrong with virt-p2v service.

Expected results:
Hide or improve this error info.

Additional info:
Attached the screenshot.
This error info doesn't show in virt-v2v-1.28.1-1.37.el7.x86_64 and livecd-p2v-201505191242.iso,refer to https://bugzilla.redhat.com/show_bug.cgi?id=1229262#c6.
Comment 2 Richard W.M. Jones 2015-08-24 07:49:47 UTC 
I suspect what may be happening here is it doesn't wait for the
network connection to come online before starting the virt-p2v
service.  By the time you'd logged in and run 'launch-virt-p2v',
the network connection had started up so everything worked.
Comment 3 Richard W.M. Jones 2015-08-24 07:56:49 UTC 
Probably this should work, but I need to test it some more:

diff --git a/p2v/p2v.service b/p2v/p2v.service

Comment 4 Richard W.M. Jones 2015-08-25 18:34:59 UTC 
Ignore comment 3 - that's wrong.

Patch series posted.  Only patch 1 is needed to fix this.

Bug 1256222
I can reproduce the bug with builds:
virt-p2v-1.28.1-1.49.1.el7
virt-v2v-1.28.1-1.49.el7.x86_64

Try to verify this bug with builds:
virt-p2v-1.28.1-1.51.3.el7
virt-v2v-1.28.1-1.51.el7.x86_64

Steps:
1.Prepare pxe to boot virt-p2v client.Add virt-p2v options in the APPEND field in the pxelinux.cfg file.
eg:
APPEND rootflags=loop initrd=initrd0.img root=live:/virt-p2v-1.28.1-1.51.3.el7.iso p2v.server=10.66.4.243 p2v.password=redhat p2v.memory=1024M p2v.name=p2v-test-nogui p2v.vcpus=1 p2v.disks=sda p2v.removable=sr0 p2v.o=disk p2v.oa=sparse p2v.of=raw p2v.os=/var/tmp rootfstype=auto ro rd.live.image quiet console=tty0 console=ttyS0,115200 rd_NO_PLYMOUTH net.ifnames=0 rd.luks=0 rd.md=0 rd.dm=0
2.Boot host from pxe.
3.Host could boot into root shell console mode and then enter into conversion mode directly without running command "launch-virt-p2v" by manual, but conversion mode still has bug:1229386 "virt-p2v in non-GUI mode doesn't show any conversion progress or status"
4.Press" ctrl+alt+F1" to enter into terminal mode and run command "journalctl -u p2v --follow ", it will show conversion process and has no error as bug 1256222
4.Check logs in virt-p2v server(10.66.4.243),the conversion has been started

Result:
virt-p2v no GUI mode could convert guest automatically
