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.

Doc Type: Enhancement
Doc Text:
.`virt-v2v` can now use vmx configuration files to convert VMware guests The `virt-v2v` utility now includes the `vmx` input mode, which enables the user to convert a guest virtual machine from a VMware vmx configuration file. Note that to do this, you also need access to the corresponding VMware storage, for example by mounting the storage using NFS. It is also possible to access the storage using SSH, by adding the `-it ssh` parameter.

Description Bill Helgeson 2017-04-11 12:25:15 UTC 
Description of problem: Having access to the VMware folders where the vmx live I would like the ability to use the vmx file as a source. Getting around the need for the export to OVA would be a great time saver to the entire migration/conversion process.


Version-Release number of selected component (if applicable): any version but 7.3 forward.


How reproducible: currently this would be a feature request.


Steps to Reproduce:

Additional info: Currently this would be used at Intermountain and Amex accounts.
Comment 2 Richard W.M. Jones 2017-04-11 13:41:36 UTC 
Dev-acking this for RHEL 7.4.

We may not actually ship it for RHEL 7.4 (except for the customer
involved in this case).

I have a half-working implementation at the moment.

Comment 6 kuwei@redhat.com 2017-04-20 07:36:42 UTC 
Verify the bug with below builds:
virt-v2v-1.36.3-3.el7.x86_64
libvirt-3.2.0-2.el7.x86_64
qemu-kvm-rhev-2.8.0-6.el7.x86_64

Verify steps:
1:Ability to convert Virtual Machines via vmx is a new feature ,and we can check it in virt-v2v manpage.
#man virt-v2v
------------------------
INPUT FROM VMWARE VMX
Virt-v2v is able to import guests from VMware’s vmx files. This is useful where VMware
virtual machines are stored on a separate NFS server and you are able to mount the NFS
storage directly.

If you find a folder of files called guest.vmx, guest.vmxf, guest.nvram and one or more
.vmdk disk images, then you can use this method.

VMX: REMOVE VMWARE TOOLS FROM WINDOWS GUESTS
For Windows guests, you should remove VMware tools before conversion. Although this is
not strictly necessary, and the guest will still be able to run, if you don't do this
then the converted guest will complain on every boot. The tools cannot be removed after
conversion because the uninstaller checks if it is running on VMware and refuses to
start (which is also the reason that virt-v2v cannot remove them).

This is not necessary for Linux guests, as virt-v2v is able to remove VMware tools.

VMX: GUEST MUST BE SHUT DOWN
The guest must be shut down before conversion starts. If you don't shut it down, you
will end up with a corrupted VM disk on the target. With other methods, virt-v2v tries
to prevent concurrent access, but because the -i vmx method works directly against the
storage, checking for concurrent access is not possible.

VMX: MOUNT THE NFS STORAGE ON THE CONVERSION SERVER
Virt-v2v must be able to access the .vmx file and any local .vmdk disks. Normally this
means you must mount the NFS storage containing these files.

VMX: IMPORTING A GUEST
To import a vmx file, do:

$ virt-v2v -i vmx guest.vmx -o local -os /var/tmp

Virt-v2v processes the vmx file and uses it to find the location of any vmdk disks.
--------------------------
2:From the manpage content ,if we want convert Virtual Machines via vmx,we should be able to access to the NFS storage directly(VMware virtual machines are stored on the NFS storage).
So mount the NFS storage to testing PC local as below:
#mount 10.73.197.27:/vol/s3/v2v/esx5.5 /mnt
3:Then we can list all the VMware virtual machines in the NFS server
# ls
