Fixed upstream with commits 649f439cb78f12bb04ef90d83b81e1fa23495852 baa4ec6e4536be971d482af76f7dca89e74573a7 74f0b45ddf35f1cb1684702e9d3318d77fc3b520 (the actual fix) Bug 1230412 I can reproduce the bug with build: libguestfs-1.28.1-1.49.el7 Try to verify this bug with package: libguestfs-1.28.1-1.50.el7 Steps: 1. Create a RHEL 6.7 guest, name:rhel6.7-mxie. 2. Add a second entry to /boot/grub/menu.lst which contains a bogus kernel: title [...] kernel /vmlinuz-2.6.32-431.11.2.el6.x86_64.x86_64 [...] 3. Try to convert the guest using virt-v2v. It is converted with warning as below # virt-v2v -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export -b rhevm -n rhevm rhel6.7-mxie [ 0.0] Opening the source -i libvirt rhel6.7-mxie [ 0.0] Creating an overlay to protect the source from being modified [ 0.0] Opening the overlay [ 93.0] 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. This probably means the NFS client or idmapd is not configured properly. You will have to chown the files that virt-v2v creates after the run, otherwise RHEV-M will not be able to import the VM.

Description of problem: The attached virt-v2v log comes from a customer case where a RHEL 6 guest has a /boot/grub/menu.lst file containing a bogus kernel: title [...] kernel /vmlinuz-2.6.32-431.11.2.el6.x86_64.x86_64 [...] This entry is the second entry in the grub config so it is probably not used. In this situation virt-v2v fails with: virt-v2v: error: libguestfs error: statns: /boot/vmlinuz-2.6.32-431.11.2.el6.x86_64.x86_64: No such file or directory It should instead warn on this but continue. Version-Release number of selected component (if applicable): virt-v2v 1.28.1-1.18.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create a RHEL 6 guest. 2. Add a second entry to /boot/grub/menu.lst which contains a bogus kernel. 3. Try to convert the guest using virt-v2v. Reported by: James Mighion
