Hi, I have a KVM host running ubuntu 18.04 with libguestfs-tools version 1.36.13-1ubuntu3.3 installed from the Ubuntu's repo and when I try to use virt-cat for example on a VM it fails with: libguestfs: error: appliance closed the connection unexpectedly. > libguestfs: error: guestfs_launch failed. After doing "export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1" and running the

I've pushed this change already actually. No one seems to know if this option is safe. If you see strange timing-related things happening in libguestfs, let us know! Rich.

Hello everyone, I wasn't planning on sending out v0.4 until ENOSPC was fixed, but Frank Groeneveld narrowed down a bug with the file data checksumming code on highmem 32bit machines. Basically the way I was using cryptomgr made it incorrectly calculate checksums on highmem pages. So to simplify things, I've switched over to plain libcrc32c. Anyone running on a 32 bit with highmem is going to hit this bug. Now you only need to compile: CONFIG_LIBCRC32C=m Into the main kernel (static is also fine). v0.4 has m...
