It turns out we need to use virDomainGetXMLDesc with the VIR_DOMAIN_XML_SECURE flag, otherwise passwords are not included in the output. https://libvirt.org/html/libvirt-libvirt-domain.html#virDomainGetXMLDesc This also requires that we use a r/w connection. As this should be simple to fix, I'll have a go at fixing this for RHEL 7.1 (if there is time). Old virt-v2v did pass this flag:
my $dom = new XML::DOM::Parser->parse($domain->get_xml_description(1));
but as you can see it's not exactly clear(!) since Matt used
the value '1' instead of the defined constant.
Patch posted: https://github.com/libguestfs/libguestfs/commit/dfded7c94118e8888dec38f11c2af62d8156a59e A further change is needed: using 'passwd=' instead of 'password=' in the output XML. In full, the following 3 commits are needed: https://github.com/libguestfs/libguestfs/commit/9c4af17add53b50ce0b6756c6216380862f10631 https://github.com/libguestfs/libguestfs/commit/dfded7c94118e8888dec38f11c2af62d8156a59e https://github.com/libguestfs/libguestfs/commit/7a218cbdf635af543479256593e448100406ea1e Tested with: libguestfs-1.28.1-1.18.el7.x86_64 virt-v2v-1.28.1-1.18.el7.x86_64 1.Prepare a guest with vnc passowrd set on xen server. 2.Use virt-v2v to convert it. 3.After conversion,the password is kept there.

Description Graphics password disappear after conversion of virt-v2v Old version of virt-v2v keeps vnc or spice password after conversion. Version: virt-v2v-1.28.1-1.17.el7.x86_64 libguestfs-1.28.1-1.17.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Before conversion：set a vnc or spice guest with graphics password. 2.Use virt-v2v to convert the guest: # virt-v2v -ic xen+ssh://10.66.106.64 -os default -n virbr0 rhel7 -of raw [ 0.0] Opening the source -i libvirt -ic xen+ssh://10.66.106.64 rhel7 [ 17.0] Creating an overlay to protect the source from being modified [ 31.0] Opening the overlay [ 241.0] Initializing the target -o libvirt -os default [ 241.0] Inspecting the overlay [ 251.0] Checking for sufficient free disk space in the guest [ 251.0] Estimating space required on target for each disk [ 251.0] Converting Red Hat Enterprise Linux Server release 7.0 Beta (Maipo) to run on KVM virt-v2v: This guest has virtio drivers installed. [ 315.0] Mapping filesystem data to avoid copying unused and blank areas [ 316.0] Closing the overlay [ 316.0] Copying disk 1/1 to /var/lib/libvirt/images/rhel7-sda (raw) (100.00/100%) [ 393.0] Creating output metadata Pool default refreshed Domain rhel7 defined from /tmp/v2vlibvirt01d9a1.xml [ 394.0] Finishing off 3.After conversion,try to boot the guest,no graphics password asked before login. Actual results： Graphics password disappear after conversion of virt-v2v Expected results: Graphics password is kept there after conversion of virt-v2v as old version of virt-v2v does. Additional info: After conversion by old version of virt-v2v,vnc or spice password will be asked before login.
