Description of problem:
[RFE]Guests should have network after v2v conversion if source vmware guest's network is connected to a distributed switch

Version-Release number of selected component (if applicable):
virt-v2v-2.0.7-6.el9.x86_64
libguestfs-1.48.4-2.el9.x86_64
libvirt-libs-8.7.0-1.el9.x86_64
qemu-img-7.1.0-1.el9.x86_64
nbdkit-server-1.30.8-1.el9.x86_64
libnbd-1.12.6-1.el9.x86_64
guestfs-tools-1.48.2-5.el9.x86_64



How reproducible:
100%

Steps to Reproduce:
1.Prepare a VMware guest and assign a network which is connected to a distributed switch of ESXi host to the guest

# cat esx7.0-rhel8.4-with-VDS-network.vmx |grep ethernet
ethernet0.virtualDev = "vmxnet3"
ethernet0.dvs.switchId = "50 34 26 b2 94 e9 3b 16-1d 68 87 bf ff 4a 54 39"
ethernet0.dvs.portId = "7"
ethernet0.dvs.portgroupId = "dvportgroup-1285"
ethernet0.dvs.connectionId = "40347428"
ethernet0.shares = "normal"
ethernet0.addressType = "vpx"
ethernet0.generatedAddress = "00:50:56:b4:ed:5a"
ethernet0.uptCompatibility = "TRUE"
ethernet0.present = "TRUE"

2.Use virsh to dump the guest xml from VMware
# virsh -c vpx://root.227.27/data/10.73.225.34/?no_verify=1 dumpxml esx7.0-rhel8.4-with-VDS-network
Enter root's password for 10.73.227.27: 
<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
  <name>esx7.0-rhel8.4-with-VDS-network</name>
.....
<interface type='vds'>
      <mac address='00:50:56:b4:ed:5a' type='generated'/>
      <source switchid='503426b2-94e9-3b16-1d68-87bfff4a5439' portid='7' portgroupid='dvportgroup-1285' connectionid='40347428'/>
      <model type='vmxnet3'/>
    </interface>
......


3. Convert the guest from VMware to rhv by v2v
#  virt-v2v -ic vpx://root.227.27/data/10.73.225.34/?no_verify=1  -it vddk -io vddk-libdir=/home/vddk7.0.3 -io  vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21 -o rhv-upload -oc https://dell-per740-22.lab.eng.pek2.redhat.com/ovirt-engine/api  -op /home/rhvpasswd  -os nfs_data -ip /home/passwd esx7.0-rhel8.4-with-VDS-network  --mac 00:50:56:b4:ed:5a:bridge:ovirtmgmt -v -x |& tee > v2v-convert-guest-with-distributed-switch-no-entry-network-name.log
█ 100% [****************************************]

4. Check the guest after conversion, found guest has no network, pls refer to attached screenshot

Actual results:
Guests don't have network after v2v conversion if source vmware guest's network is connected to a distributed switch

Expected results:
As above description

How exactly is this done on the vmware webui?

Is it at all possible on the basic esx webui, or does it require the thick vsphere client?

(Same questions for bug 2125556.)

Thanks!

1. Create a VDS on vsphere web client according to https://www.nakivo.com/blog/vmware-distributed-switch-configuration/
2. Add a new network device which is connected to DPortGroup to a guest, pls refer to screenshot 'vmware-guest-with-vds-network.png'
