[Xen-devel] vmx status report against changeset 14356 - 1 new issue
Hi,All
We have tested the latest xen on VT platform with Intel 915/E8500
chipset.
Two platforms (PAE/32E) test all are based on SMP, It means that we boot
up SMP guest OS in VMX.
Here is the test summary:
New issue (1)
===============================================1) Fails to restore VMX guests
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=929
Issues List (3):
================================================1) IA32E/PAE: 32bit Vista RTM
network doesn''t work.(p2)
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=840
2).time latency is a negative number on window guest when vcpu > 1
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=895
You can reproduce it on SMP windows, it will not happen on UP
Windows
3) Xen0 Crash after run case ia32e_smp_vista many times (p1)
the ia32e_smp_vista will fail one time after about repeating 6
times, Xen0 will crash after repeating this case more than 10 times.

hi
I try to understand to the code of scheduler/scheduler-sedf
I am confused about how does scheduler-sedf work
I donot know how does the scheduler-sedf related struct be organized
and their functions
such as the mean and function of the idle in struct of schedule_data
and what about the runnableq/waitq in struct of sedf_cpu_info
could you tell me about how does scheduler-sedf related struct be
organized to work in general
I look the code but confused
could you help me
Thanks in advance
struct schedule_data {
spinlock_t schedule_lock; /* spinlock protecting
curr */
struct vcpu *curr; /* current
task */
struct vcpu *idle; /* idle task for this
cpu */
void *sched_priv;
struct timer s_timer; /* scheduling
timer */
unsigned long tick; /* current periodic
''tick'' */
} __cacheline_aligned;
struct sedf_cpu_info {
struct list_head runnableq;
struct list_head waitq;
struct list_head extraq[2];
s_time_t current_slice_expires;
};

hi I try to understand the code of VMcreate where does the xc_get_pfn_list( ) further go to? I am confused does xc_get_pfn_list finally go to the function arch_do_domctl() or not? I am lost in the xc_get_pfn_list() and the function of xc_get_pfn_list() is to allocate the phymemframe to the VM which is going to be booted up ,am I right? I am confused about it could you help me Thanks in advance _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Thank you for your guide and now I find the related code I have read this part code of xen3.0.2 a few days ago,but did not understand it well and I read this part code in xen3.0.3 this time ,and there are some change in this part I am confused by the difference between my memory and the code,and thank you for your guide I look through it Thank you for help Daniel Stodden 写道:> On Fri, 2007-03-16 at 11:46 +0800, tgh wrote: > >> hi >> I try to understand the code of VMcreate >> > > not sure what VMcreate means. are you looking at the xend code? > > >> where does the xc_get_pfn_list( ) further go to?
