Created attachment 1071671 [details] Screenshot1 for AVG installed Description of problem: No warning shows when convert a win7 guest with AVG AntiVirus installed Version-Release number of selected component (if applicable): libvirt-1.2.17-8.el7.x86_64 libguestfs-1.28.1-1.52.el7.x86_64 virt-v2v-1.28.1-1.52.el7.x86_64 qemu-kvm-rhev-2.3.0-22.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. Prepare a win7 guest with AVG AntiVirus installed. Download link: http://www.avg.com/cn-zh/china-home See screenshot1. 2. Use virt-2v convert this guest to rhevm. # virt-v2v -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export -n rhevm kvm-win7-x86_64-qcow2 -of raw -on win7-AVG [ 0.0] Opening the source -i libvirt kvm-win7-x86_64-qcow2 [ 0.0] Creating an overlay to protect the source from being modified [ 0.0] Opening the overlay [ 2.0] Initializing the target -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export virt-v2v: warning: cannot write files to the NFS server as 36:36, even though we appear to be running as root.

In some circumstances, AV may prevent new drivers from working (resulting in a 7B boot error). If this happens, try disabling AV before doing the conversion.
