Description of problem:
There is no info "Opening the source -i libvirt -ic vpx://..." shown if any IP is wrong in vpx:// URL during v2v conversion

Version-Release number of selected component (if applicable):
virt-v2v-1.42.0-3.module+el8.3.0+6497+b190d2a5.x86_64
libguestfs-1.42.0-1.module+el8.3.0+6496+d39ac712.x86_6

How reproducible:
100%

Steps to Reproduce:
Scenario1:
1.1 Convert a guest from VMware by v2v but write incorrect vCenter IP in command line, found there is no info output more than 2mins until the conversion is failed with error, besides, there is no debug info "Opening the source -i libvirt -ic vpx://root@......" shown during conversion

1.1.1 # virt-v2v -ic vpx://root.198.169/data/10.73.199.216/?no_verify=1 -it vddk -io vddk-libdir=/home/vmware-vix-disklib-distrib -io vddk-thumbprint=B5:52:1F:B4:21:09:45:24:51:32:56:F6:63:6A:93:5D:54:08:2D:78 esx7.0-win2019-x86_64 -ip /home/passwd -o null
virt-v2v: error: exception: libvirt: VIR_ERR_INTERNAL_ERROR: VIR_FROM_ESX:
internal error: Could not find compute resource specified in
'/data/10.73.199.216/'

If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:

  virt-v2v -v -x [...]


1.1.2 Add -v -x to convert again, can see the error info is reported after more than 2mins

Scenario2:
2.1 Convert a guest from VMware by v2v but write incorrect ESXi IP in command line, v2v will report the error info immediately but there is also no debug info "Opening the source -i libvirt -ic vpx://root@......" shown
