The problem is with the inspection data for this guest: i_root = /dev/sda1 i_type = windows i_distro = windows i_arch = x86_64 i_major_version = 6 i_minor_version = 0 i_package_format = unknown i_package_management = unknown i_product_name = Windows Server (R) 2008 Standard i_product_variant = unknown i_uefi = false product-variant is "unknown", but virt-v2v expects to match "Server" here, hence it does not find the driver. Inspection reads the product variant from HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion in a key named InstallationType, but for this guest that key was not found. Upstream fixes: https://github.com/libguestfs/libguestfs/commit/a324ae2ad72f2a2188eb0d4398c9e6548c499c5a https://github.com/libguestfs/libguestfs/commit/9f0036a0265417bc7fd6e6d2010f185a4a92d225 Actually my test W2K8R2 machine has: "InstallationType"=str(1):"Server" But the patch still seems to be fine as we have found a Windows machine that lacks InstallationType. Tested with:
libvirt-1.2.16-1.el7.x86_64
virt-v2v-1.28.1-1.42.el7.x86_64
qemu-kvm-1.5.3-92.el7.x86_64
Use virt-v2v to convert windows 2008 guest to rhev and libvirt,the virtio drivers are all installed.

After conversion,boot guests and check virtio drivers in guest,for both disk and network,it shows as virtio.

Actual results: As description. Expected results: Virtio drivers are installed for win2008/win2008r2 guest. Additional info: 1.Attached the debug info. 2.Other windows like win7 and win2003 works well.
