Debian kernels have disabled legacy vsyscall page support meaning they cannot runs binaries that predate c.2013. To enable it again you must add vsyscall=emulate to the kernel command line when booting. It's unclear why Debian disabled this as according to the documentation: Disabling this option saves about 7K of kernel size and possibly 4K of additional runtime pagetable memory.

Use -ip instead of --password-file, and various refactorings. It strikes me that we should probably deprecate and eventually remove virt-v2v-copy-to-local. With the introduction of the new SSH and VDDK transports, and with RHEL 5 Xen becoming more irrelevant, it's no longer needed. Rich.
