about memory alloc
Hi,
I have a question, If I start 2 or more guest linux, does the physical memory of code segment and readonly data segment be reused?
What''s the relationship between the physical memory and the number of guest os that can create?

question about page_to_phys
The page_to_phys is defined as
#define page_to_phys(page) (phys_to_machine(page_to_pseudophys(page)))
so it return machine addresss
while virt_to_phys return psedophys. include/asm-xen/asm-i386/io.h
this is really confusing.
why not define page_to_machine?

[PATCH]rtc emulation for xenU
...hen the rc scripts run
the command hwclock. The patch attached resolves the issue.
The patch adds a simple rtc emulation and also on i386, hwclock can get
correct date when xenU enabled pirq binding, without this patch, hwclock
read will timeout because of lack of update interrupt.

Performance Specs
Hi all.
Are there any specs about performance of Asterisk?
I want to know how many simultaneous SIP/VoIP connections
on one Linux box.
I don't care whether official specs or user tested specs.
Thanks in advance,

Should shadow_lock be spin_lock_recursive?
During our testing, we found this code path where xen attempts to grab
the shadow_lock, while holding it - leading to a deadlock.
