After step by step monitoring, I get the following statistics about hypercall
entries:
numbers | hypercalls | executed bytes (offset to hypercall entry) 7755 24: 0

For following hypercall page initialise code, where would the execution jumps
at syscall? How can I predict what is the execution order of "pop %r11"? Is it
the fifth instruction/step? I need the order to precisely set up hooks to
monitor hypercalls.

I've got the hypercall_page_initialize function as follows. As the size of each
hypercall page entry is 32B and the initialize function only assigns value to
the first 8B, is the remaining space empty or initialized afterwards?

Hello, recently I'm looking into the code of nested xen under
/xen/arch/x86/mm/hap, here are some questions which I hope to get help from you.
1. About nested ept. Is the memory translation process like this: L2 VA --> L2
PT --> L2 PA --> L1 EPT --> L1 VA --> L1 PT --> L0 EPT --> MA? What's the

Happy Holiday, guys. God tell me that I should work this out before celebrate ;
)I create a HVM first, then compile Xen on it. The dom0 of this Xen is a PV. So
is this nested xen a HVM or a PV? It's hard to differentiate when concerning to
enable events as only HVM supports events.

This is the output when I tried to create a vm in a nested xen. I looked up
into the source and found error -22 presents invalid arguments. What might be
the cause?
(XEN) event_channel.c:272:d0 EVTCHNOP failure: domain 1, error -22(XEN)

Sorry for the late reply, there is something wrong in network which makes the
email not delivered successfully.The inject method is by using
xc_map_foreign_range to map the address of the nested xen and memcpy the trap
to the specific location. If there is a problem, it should be the

I tried to debug xen use kdb. After compiling xen with debug=y, is there any
further steps I should take? I can get console outputs start with:Xen
4.4.1(XEN) Xen version 4.4.1 (root@) (gcc (Ubuntu 4.8.4-2ubuntu1~14.04)
4.8.4) debug=y Wed Dec 16 11:01:14.But I can't
In a multiple cpus machine where each vcpu is pinned at the corresponding
physical cpu, a VM's context can be obtained through the cr3 of the
corresponding vcpu. However, what if a nested xen is presented? Does the nested
xen shared vcpus with the VMs on it or occupy a separate one? How can I
I can debug xen using console connections. However, HVM nested xen seems to not
support 'xl console'. Even though I set the console according to
http://www.dedoimedo.com/computers/xen-console.html, it still cannot output xen
related infomation. Any suggestions?
Which routine xen uses when translate nested xen address ? The first one or the
second?
1. nested vm -->EPT1 of L1 xen --> EPT0 of L0 xen --> machine address
2. nested vm --> EPT1 of L1 xen --> machine address
Does the nested vm directly translate its virtual address by vEPT or through
two EPT
Thanks for your reply. I've already changed to boot with the xen.efi directly
without grub2. Now I can see all the cpu cores, but I can't use the mouse or
keyboard. What's more, the memory seems to be problematic too. 'xl dmesg' shows
:
(XEN) Unknown cachability for MFNs 0x8-0x8(XEN)
Sorry, I thought they are due to same reason so I put them together. Maybe I
should just solve them one by one. Full log is here
