Hi all, I start the domU with linux 4.12.13(bzImage) and xen 4.9.0, and I manually dump the guest memory with `sudo xl dump-core myvm dump-res`. Then I try to analyze it in crash using sudo crash bzImage dump-res, but it tells me that crash: bzImage: not a supported file format I have tried to add `-f` option using `sudo crash -f bzImage dump-res`, but get the same error. I then replace the bzImage with corresponding vmlinux, this time it gives me the following message WARNING: cannot read linux_banner string crash: src/linux-4.12.13/vmlinux and dump-res do not match! How can I make them match? Xen does not support directly boot a uncompressed vmlinux file(in HVM mode) so I have keep using bzImage. Thanks Zihan
