Hi All,
I am a newbie to xen. As I was going through xen debugging commands, I
came across " key A => toggle alternative key handling" and "key % => trap
to xendbg". Can anyone please explain me the functionality of these two
debugging features?
Regards
Gokul

Hi list,
I'am struggling with a hypervisor panic. The hypervisor version is 4.4.3,
yes I know - very old ;-), but the affected code hasn't much changed.
The panic was never seen before and occured while booting the system,
only dom0 was running.

Hi,alls.
in xen-4.4.1/tools/libxc/xc_domain_save.c,the function
xc_domain_save(),there are two function xc_report_progress_start()
and xc_report_progress_step().And so as xc_domain_restore().
I don't know the function of these two functions,has anyone can tell me?
thanks
I'm modifying the source code of snapshot,in the function xc_domain_save()
of xc_domain_save.c,through calling wrexact() to copy the memory pages to
the local dist.
I'm not sure if it is the answer you wang.

I'm also working on a similar thing - can you please tell me how you copy
the memory pages from one part of the memory to another?

Hi,alls
I'm modifying the source code of xen-4.4.1. Specifically, I'm modifying the
memory copy part of snapshot. I first put all memory pages to write
protection, and then rewrite the write protection exception part of the
code. After capture the exception then save the memory page , and all

Hi Wei,
Thanks for your reply. Sorry I did not change the comment properly.
These are the two methods I tried separately.
First method:
I see /dev/hvc1 and /dev/hvc2 being created when I give two
channels in the guest xl config file. So I wrote a program to open
hvc1 and read like below.

Hello,
Please let me know if you have some information about issue below.
I created a channel device for PV guest using
channel= ["connection=pty, name=xen.channel.0,
path=/var/lib/xen/ctl-socket","connection=socket, name=xen.channel.1,
path=/var/lib/xen/ctl-socket-data"]

Hello,
Issue in tapdisk-vbd.c
Why td_queue_write(parent,treq); is called in static void
__tapdisk_vbd_reissue_td_request(td_vbd_t *vbd,td_image_t *image,
td_request_t treq) function as we can't write in parent vhd because it is
read only.
I have attached the code of tapdisk-vbd.c and block-vhd.
Hi,
Does Xen-4.4.1 or later version support PIIX4 IDE interface. Going through
the Xen code it looks like it is supported but when I try booting a Linux
VM it comes up with PIIX3 IDE interface. Please let me know if PIIX4 IDE
is supported and can be configured in some way.

xen_emul_unplug=unnecessary (kernel arg) may help you here.
Also udev likes to rename your devices.
