Hi rjones, 

   The command line which is used to generate attached log file is 
"# virt-v2v  -ic vpx://vsphere.local%5cAdministrator.73.141/folder-m/dc-m/cluster-m/10.73.75.219/?no_verify=1 -ip /home/passwd esx6.7-rhel7.8-x86_64 -v -x |& tee > administrator-account-without-vddk.log "

  Below is similar v2v conversion which uses same vSphere client structure with above command but uses root account

Preliminary patch posted:

https://www.redhat.com/archives/libguestfs/2020-June/thread.html#00086

This just disables readahead and I'm still testing it.

I posted the patch again as part of:
https://www.redhat.com/archives/libguestfs/2020-September/msg00184.html

Having the same issue [1] on EL8.2 (RHV Host) with:

- libguestfs-1.42.0-2.module+el8.3.0+6798+ad6e66be.x86_64

PS> Importing the same VM using the RHV-UI works as expected even though
the same url error appears in the import log - import log attached.

I'm starting to think that the issue behind these failures is not due to the VMware user used for the conversion. I personally can perform conversions using a non-administrator user with the right roles enabled.

One common thing of all these failures is that the VMware instances are QE resources, and thus used for testing using automated and manual jobs on them. Because of them, there may be various sessions open with the vCenter instance at the same time.
According to some old sources [1], it looks like there is some kind of limit for SDK sessions, although I cannot find a way to either get this limit or fetch statistics on the active sessions.

[1] https://communities.vmware.com/t5/vSphere-Management-SDK/Max-SOAP-sessions/m-p/1534369

So: Ming, Beni, Tamir: please try to convert again, monitoring the logson the vCenter appliance for possible errors like explained in these two VMware KB articles:
- https://kb.vmware.com/s/article/50114010
- https://kb.vmware.com/s/article/1031039

Do you get any of the errors mentioned in the articles?

I've disabled readahead for VMware-over-https upstream:
https://github.com/libguestfs/virt-v2v/commit/9f4940068022d4e7abdfea6617b73a2b206f19aa

I've also enabled cookie-scripts support which should help with
authentication timeouts:
https://github.com/libguestfs/virt-v2v/commit/2b9a11743b74ef3716b66a7e395108a26382e331

I found this error on the VMware's VCenter 7 server, in the file /var/log/vmware/vpxd/vpxd.log.
It looks like virt-v2v creates too many HTTP sessions to the VCenter and it results in 503 error in VMware's VCenter services.

* Workaround for the HTTP method *
I found a workaround to allow VCenter to accept as many sessions as possible you can change the file /etc/vmware-vpx/vpxd.cfg on the VCenter's server
and add inside the <vmacore> XML tag the following XML:
"
    <soap>
      <maxSessionCount>0</maxSessionCount>
    </soap>
"

You shouldn't replace all the <vmacore> contents, just add the above lines inside.
It will look something like that:

"
  <vmacore>
    <cacheProperties>true</cacheProperties>
    <soap>
      <maxSessionCount>0</maxSessionCount>
    </soap>
    <ssl/>
    <threadPool>
      <TaskMax>90</TaskMax>
      <threadNamePrefix>vpxd</threadNamePrefix>
    </threadPool>
  </vmacore>

"

Thanks, I've added this to the virt-v2v documentation to help others
who have this problem in future:

Hi Richard W.M. Jones: 

Description of problem:
There is nbdkit curl error info if convert a guest from VMware to oVIrt during import.

nbdkit: curl[3]: error: problem doing HEAD request to fetch size of URL [https://<vcenter>/folder/tdfdettsovr002s/tdfdettsovr002s-flat.vmdk?dcPath=TTCE-CC03-RESOURCE&dsName=vol%5fvm%5fd2esr1%5fcdc03%5f14%5fkbe08]: HTTP response code said error: The requested URL returned error: 503 Service Unavailable

It does retry for 5 times and eventually it fails, I see that some of the patches being worked by Redhat team and you. When the virt v2-v patch would be released. Appreciate your help.

I see the latest version of  virt-v2v is 1.42.0, when the remediation of above problem is expected.

It has become blocker for us to move to oVIrt. Please let me know if you need any more details.

That patches are all open source.  See comment 22 for the one which documents
how to fix this bug.

So I've partially resolved this bug in AV 8.5.0 by cherry picking:

9f4940068022d4e7abdfea6617b73a2b206f19aa
v2v: Disable readahead for VMware curl sources too (RHBZ#1848862).

00649e98be43b4b05a28c5c8c858a54ec4fe3e7a
docs: Document how to remove "Out of HTTP sessions" limit.

However the main fix here -- using cookie-scripts -- is not backportable
to RHEL 8 because related changes would require us to remove the
virt-v2v-copy-to-local tool.  This tool has been removed in RHEL 9
but I don't want to remove the tool from RHEL 8.

For the complete fix you're going to have to move to RHEL 9 or
the upstream package.

Test the bug with below builds:
virt-v2v-1.42.0-11.module+el8.5.0+10793+d881d728.x86_64
libguestfs-1.44.0-3.module+el8.5.0+10681+17a9b157.x86_64

Hi Richard,

I know!  The main fix can't be done til RHEL 9 (see comment 27).  I only
backported a few patches that are possible in RHEL AV.

If you want we can move this bug to RHEL 9 where it's already been fixed
(comment 25).

Oh sorry, I didn't read the comment27 carefully, but seems the patches "v2v: Disable readahead for VMware curl sources too" and "docs: Document how to remove "Out of HTTP sessions" limit" have little effect for the bug, did I miss anything for the bug?


1.Check man page "virt-v2v-input-vmware" and found below info:
# man virt-v2v-input-vmware |grep "Out of HTTP sessions: Limited to ..." -A 7
   vCenter: "Out of HTTP sessions: Limited to ..."
       VMware vCenter appears to limit HTTP sessions and in some circumstances virt-v2v may exceed this number.  You can adjust or remove
       the limit by editing /etc/vmware-vpx/vpxd.cfg on the vCenter server.  Increase the "<maxSessionCount>" field, or set it to 0 which
       makes it unlimited:

        <soap>
          <maxSessionCount>0</maxSessionCount>
        </soap>
2. Log into vCenter Server to modify /etc/vmware-vpx/vpxd.cfg but can't found info about <maxSessionCount>, 
root@vm-198-169 [ ~ ]# cat /etc/vmware-vpx/vpxd.cfg |grep "<maxSessionCount>"
root@vm-198-169 [ ~ ]# cat /etc/vmware-vpx/vpxd.cfg |grep "soap"
    <soapPort>8085</soapPort>

3.So add related info to the file manually on vCenter Server
root@vm-198-169 [ ~ ]#  cat /etc/vmware-vpx/vpxd.cfg |grep "<maxSessionCount>" -A 1 -B 1
    <soap>
       <maxSessionCount>0</maxSessionCount>

Since we haven't really fixed this, and backporting the patches to fix it
will require removing virt-v2v-copy-to-local, let's move this to RHEL 9.

Currently imports via the RHV UI are broken.  RHV will be based on RHEL8 for some time, and this functionality will no longer work.

The bug has been fixed on rhel8.6, details please refer to bug2018173

I'm also confused about what you mean by this statement.  Imports
via RHV UI should work as far as I know.

It's fixed in RHEL 8.6 which is out in May.  You'll have to ask the RHV team
if/when it'll appear in a RHV node.  They can use RHEL as a node.  For early
access see the hotfix process.

Rich, can we adjust the BZ to reflect that this was fixed in RHEL 8.6?

Abhishekh - you may need to request a z-stream if you need this fix in a released version before RHEL 8.6 (or the customer is not able/willing to upgrade to RHEL 8.6).

Hi Chen Shao, could you help to check which rhvh version contains virt-v2v version >= 1.42.0-16.el8

Sorry I was confused myself.  The RHEL 8.6 bug exists already:

Hi Mxie,
The latest RHVH is rhvh-4.4.9.4-0.20220107.0+1, and virt-v2v version is virt-v2v-1.42.0-15.module+el8.5.0+12264+1ee0d523.x86_64.
So 1.42.0-16.el8 is not included by RHVH yet.

# imgbase w
You are on rhvh-4.4.9.4-0.20220107.0+1
# rpm -qa| grep virt-v2v
virt-v2v-1.42.0-15.module+el8.5.0+12264+1ee0d523.x86_64

The version virt-v2v-1.42.0-16 is in rhvh 4.4.10. Does that mean the fix is available in this RHVH? 

~~~
[root@dhcp210-238 ~]#  rpm -qa| grep virt-v2v
virt-v2v-1.42.0-16.module+el8.5.0+13900+a08c0464.x86_64

[root@dhcp210-238 ~]# imgbase w
You are on rhvh-4.4.10.2-0.20220310.0+1
~~~

Also, the Bug status is NEW, so just wanted to confirm, is it correct?

The bug has been fixed for a long time in RHEL 9, I think this bug
just fell through the cracks.

As you're using RHEL 8, you'll need to look at this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=2018173

And this one too (z-stream clone for 8.5-z):
https://bugzilla.redhat.com/show_bug.cgi?id=2040778

Verify the bug with below builds:
virt-v2v-2.0.3-1.el9.x86_64
libguestfs-1.48.1-1.el9.x86_64
