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.

Screenshot1 for AVG installed

Description of problem:
No warning shows when convert a win7 guest with AVG AntiVirus installed 

Version-Release number of selected component (if applicable):
libvirt-1.2.17-8.el7.x86_64
libguestfs-1.28.1-1.52.el7.x86_64
virt-v2v-1.28.1-1.52.el7.x86_64
qemu-kvm-rhev-2.3.0-22.el7.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Prepare a win7 guest with AVG AntiVirus installed.
Download link:
http://www.avg.com/cn-zh/china-home
See screenshot1.

2. Use virt-2v convert this guest to rhevm.
# virt-v2v -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export -n rhevm kvm-win7-x86_64-qcow2 -of raw -on win7-AVG
[   0.0] Opening the source -i libvirt kvm-win7-x86_64-qcow2
[   0.0] Creating an overlay to protect the source from being modified
[   0.0] Opening the overlay
[   2.0] Initializing the target -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export
virt-v2v: warning: cannot write files to the NFS server as 36:36, even 
though we appear to be running as root. This probably means the NFS client 
or idmapd is not configured properly.

You will have to chown the files that virt-v2v creates after the run, 
otherwise RHEV-M will not be able to import the VM.

[   3.0] Checking for sufficient free disk space in the guest
[   3.0] Estimating space required on target for each disk
[   3.0] Converting Windows 7 Ultimate to run on KVM
virt-v2v: This guest has virtio drivers installed.
[   5.0] Mapping filesystem data to avoid copying unused and blank areas
[   6.0] Closing the overlay
[   6.0] Checking if the guest needs BIOS or UEFI to boot
[   6.0] Copying disk 1/1 to /tmp/v2v.ED40Fu/67f39ca5-5198-4da3-aad6-7d05451eee12/images/2e7c4769-3e5b-4f9f-abe1-f2f78b890a3a/d174fcac-24fb-4913-80a0-7b55e5a58e04 (raw)
    (100.00/100%)
[ 222.0] Creating output metadata
[ 222.0] Finishing off

Actual results:
No warning shows when convert a win7 guest with AVG AntiVirus installed 

Expected results:
Should show such warning like:
virt-v2v: warning: this guest has Anti-Virus (AV) software and a new virtio
block device driver was installed.  In some circumstances, AV may prevent
new drivers from working (resulting in a 7B boot error).  If this happens,
try disabling AV before doing the conversion.
