...9;m not too familiar with libguestfs logic - maybe you can point for me, according to the logs, at what stage of the conversion the failure happens.

...e really ease - I write a big file to /tmp on L0 (till it 100% full) and then run a L2 VM. Almost every time it crushes with double fault. Debugging, debugging and more debugging.

Hi everybody, Wanted to hear your opinion and to receive a smart advice. I'm trying to use virt-v2v in order to convert ova image (exported from vcenter) to run on libvirt/kvm - all this inside a VM of fedora. The converted image is also a fedora. During the conversion process, in some point of libguestfs activity, I get double fault panic from L2 (printed as part of libguest output) and the

...r5 are predictors (alternative-specific) that are columns of M; and weights is another column of M. This line works too, but it gives me the same answer as when the weights were omitted, which seems to indicate that the weights aren't properly being taken into account. Any suggestions?

Hi everybody, Wanted to hear your opinion and to receive a smart advice. I'm trying to use virt-v2v in order to convert ova image (exported from vmware) to run on libvirt/kvm - all this inside a VM of fedora. The converted image is also a fedora. During the conversion process, in some point of libguestfs activity, I get double fault panic from L2 (printed as part of libguest output) and the
