11 years agoSupport for new Palacios image file format (Version 1)
Kyle Hale [Sat, 28 Jul 2012 22:40:26 +0000]
Support for new Palacios image file format (Version 1)

The VMM configuration side and the utilities side have been updated to now support
two file formats:

Version 0 : The previous version "legacy"
Version 1 : The new version "file integrity checking"

build_vm now has an option [-v] to select versions, version 1 is the default
v3_create now creates version 1 images when dynamic construction of an image file is done

Version 1 has these changes:

add integrity checking for files included in guest configs

This patch adds a hash field to the file headers built from guest
configurations. Both methods of guest creation (in-memory with XML and
file building with build_vm) have been modified to support this. The hash
is passed along with the file when it's added to Palacios, so integrity checks
can theoretically happen at any point, but currently
this is only being done at configuration time.

11 years agorepurpose v3_ctrl.c as a utility library for palacios userspace progs
Kyle Hale [Sat, 28 Jul 2012 20:46:05 +0000]
repurpose v3_ctrl.c as a utility library for palacios userspace progs

I've taken some common idioms used in a lot of the userspace utilities
and put them in a (for now, static) library that all programs can utilize.
One example: when running an ioctl, it's no longer necessary to open the vm device,
close it, etc. This is taken care of by v3_vm_ioctl.
This should give us some more code sharing and make the userspace utilities quicker to write and a bit smaller.
For now, I've modified v3_free, v3_launch, v3_stop, and v3_create to use this library,
so you can look to those for examples.

APIC and CR8 changes for vector priorization vs TPR

This patch does the following:

- It moves the TPR into the guest core structure, replacing CR8
- It intercepts CR8 reads/writes to update the TPR accordingly
- It moves prioritization into the APIC, away from the architecture-specific
  SVM or VMX handling
- It computes APIC PPR and APR dynamically in the APIC
- It does vector to PPR priority comparison (this was not done before at all)
- It does vector to APR comparison for IPI delivery
- It updates checkpointing, etc, to reflect these changes
