implicit grant unmap
...S hooks. This crash occurs when the operating
system writes a zero to the PTE for a grant mapping without an explicit
Xen call to unmap.
In hacking around, it seems the problem is this: When the mapping PTE
gets squashed, Xen''s cleanup_writable_pagetable() has no way to find the
correct maptrack entry for the affected mapping. Consequently, the
grant mapping is not properly cleaned-up.
Sound correct? Are there worse problems here?
Thanks,
-steve

Grant Tables between dom0 and domU?
Hi All,
The interface manual says - grant tables provide a generic mechanism sharing
between domains.
Subsequent lines suggest mechanism sharing between only unpriviliged
domains.
Can grant tables be used for this capability based shared memory
communication between dom0 and domUs?
Thanks

RFC: [0/2] Remove netloop by lazy copying in netback
Hi Keir:
These two patches remove the need for netloop by performing the
copying in netback and only if it is necessary. The rationale
is that most packets will be processed without delay allowing
them to be freed without copying at all. So instead of copying
every packet destined to dom0 we''ll only copy those that linger
longer than a specified amount of time (currently 0.5s).
As it

Kernel panic with 2.6.32-30 under network activity
Hello,
I''ve got several kernel panic on a domU under network activity (multiple
rsync using rsh). I didn''t manage to reproduce it manually, but it happened
5times during the last month.
Each time, it is the same kernel trace.
I am using Debian 5.0.8 with kernel/hypervisor :
