Perhaps we should decide not to cache /dev/xvda in VMs and rely on Dom0 to do that instead, saving precious memory this way.

This is tricky:

  • Should we disable all FS caching in VM and so move more memory to Dom0 to enable better caching there (where the blockback is running)? Not clear it that would really speed things up...
  • Should we use tmem?

Turned out that disabling caching in a VM degrades performance.
