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
xen kernel should be removed from boot menu after conversion by virt-v2v

Version:
libguestfs-1.27.52-1.1.el7.x86_64
virt-v2v-1.27.52-1.1.el7.x86_64

How reproducible:
50%

Steps to Reproduce:
1.Use virt-v2v to convert a xen pv guest.
# virt-v2v -ic xen+ssh://10.66.106.64 -os default  pv-rhel58-nolvm
[   0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 pv-rhel58-nolvm
[  16.0] Creating an overlay to protect the source from being modified
[  30.0] Opening the overlay
[  52.0] Initializing the target -o libvirt -os default
[  52.0] Inspecting the overlay
[  76.0] Checking for sufficient free disk space in the guest
[  76.0] Estimating space required on target for each disk
[  76.0] Converting Red Hat Enterprise Linux Server release 5.8 (Tikanga) to run on KVM
This guest has virtio drivers installed.
[  90.0] Mapping filesystem data to avoid copying unused and blank areas
[  91.0] Closing the overlay
[  91.0] Copying disk 1/1 to /var/lib/libvirt/images/pv-rhel58-nolvm-sda (raw)
    (100.00/100%)
[ 216.0] Creating output metadata
Pool default refreshed

Domain pv-rhel58-nolvm defined from /tmp/v2vlibvirtfa2d3e.xml

2.After conversion,boot the guest.
# virsh start pv-rhel58-nolvm

3.After boot the guest,check the boot menu,there are still 2 kernel:both regular kernel and xen kernel.

Actual results：
As description.

Expected results:
xen kernel should be removed from boot menu after conversion by virt-v2v

Additional info:
If try to boot xen kernel,it will fail with error.
Comment 1 Richard W.M. Jones 2014-09-23 10:44:37 UTC 
As this is cosmetic, I'm going to cond NACK (capacity) and
defer to a later RHEL release.
Comment 2 Richard W.M. Jones 2015-04-20 12:24:05 UTC 
Since this involves more risky edits to the grub configuration
of the guest, I'm not going to do this.  There's too much risk
that removing bits from the grub config will break the guest or cause
conversion failures.

virt-v2v should (and currently does) select the correct non-Xen
kernel as default, so the guest will boot after conversion without
interaction [if that was not the case, it would be a bug].

If users manually select alternate Xen kernels and try to boot
with them, then that's just too bad.
