Description Support conversion of guest using grub2 Version: libvirt-1.1.1-10.el7.x86_64 virt-v2v-0.9.1-4.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.Prepare a fedora 19 guest which using grub2. 2.Use virt-v2v to convert it. # virt-v2v -ic qemu+ssh://10.66.72.24/system -os default grub2-test grub2-test.img: 100% [=================================================================================]D 0h03m32s Didn't find modules directory /lib/modules/0-rescue-030b8ef508f9c11e5a76aaed048f5bbc for kernel /boot/vmlinuz-0-rescue-030b8ef508f9c11e5a76aaed048f5bbc Use of uninitialized value $version in concatenation (.) or string at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm line 1138. Use of uninitialized value $kernel in concatenation (.) or string at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm line 2470. virtio configured, but no virtio kernel found at /usr/share/perl5/vendor_perl/Sys/VirtConvert/Converter/RedHat.pm line 1007. Actual results： As description. Expected results: virt-v2v can convert guests using grub2 Additional info:
Bug 1059386 also hit the same error. So I think the error is caused by something in grub conf which virt-v2v doesn't aware.
Hi, Matthew Help uday make a needinfo to you. Please take a while to consider if we support guest conversion with grub2 or any other grub setting in RHEL6.6 Regards, Lei
The root cause here is that _inspect_linux_kernel can return undef if it can't identify useful information about the kernel, but nowhere that calls it handles this.
Virt-v2v needs to run on the latest Red Hat Enterprise Linux release to ensure it can correctly read and modify new guest filesystem features. A new version of virt-v2v is now available for RHEL 7.1. Before RHEL 7.1 is released, follow the instructions here to install unsupported preview packages on top of RHEL 7.0: https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html After RHEL 7.1 is released, virt-v2v will be available in Technical Preview. You can run virt-v2v in a single virtual machine. Other requirements are covered here: http://libguestfs.org/virt-v2v.1.html#resource-requirements If you find a missing feature or bug in the new version of virt-v2v please file a bug using the following link: https://bugzilla.redhat.com/enter_bug.cgi?product=Red%20Hat%20Enterprise%20Linux%207&component=libguestfs
