Optional starting address for v3_mem

The idea here is that on hosts that already have a lot of stuff
running, it may be very costly to offline memory blocks low in the
physical address space - the kernel may take a looong time to copy
their contents and set things up accordingly.  With this patch, you can say
things like:

v3_mem 1024 1024

which means that you are looking to allocate 1024 MB of space
starting at or above the address 1024*(1024*1024)

Peter Dinda [Sat, 29 Dec 2012 18:59:47 +0000]
Context-based output infrastructure (V3_Print, etc) and modifications to use it

This commit is huge, but the vast majority of it is basically trivial changes in
how V3_Print, PrintDebug, PrintError, V3_ASSERT, and Vnet_Print are invoked
throughout our codebase. All compiles, with all debug and features enabled.
Functionality testing doesn't show problems.

These functions now include a context: the VM and the vcore.  There are
Several cases:

V3_Print(vm, vcore, ...)           => VM-specific, and vcore-specific
V3_Print(vm, VCORE_NONE,...)       => VM-specific, but not core specific
V3_Print(VM_NONE, VCORE_NONE),...) => non-specific

PrintDebug now prefaces data with DEBUG:
PrintError now prefaces data with ERROR:
Telementry prefaces with telem.# (as before)

The print OS hook has been modified so that it is called with:

print(void *host_priv_data_from_create, // NULL = non-specific
      int vcore_number,                 // -1 = non-specific
      ...)

The linux implementation now uses this functionality to decorate its
output in an enhanced way:

palacios (pcore num): ...
palacios (pcore num vm name): ...
palacios (pcore num vm name vcore num):...

The new userspace tool v3_info filters and formats dmesg or /proc/kmsg
output in numerous ways so that you can, for example, focus on the
debugging output of a specfic core on a specific VM. Run without
arguments for help.

Other minor compilation fixes for ancient code.

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.

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
