Then i'm use qemu-xen-traditional
And start simple domain:
name="170131-10018"
vif="mac=00:16:3e:00:21:98,ip=62.76.184.141"
disk="phy:/dev/disk/vbd/170131-18,xvda,w"
memory=2048
maxmem=2048
vcpus=4
maxvcpus=4
cpu_cap=400
cpu_weight=2048
vfb="type=vnc,vncpasswd=x0boskQNan"
with kernel inside domU 2.6.32-220-el6 (centos 6 stock kernel)
and worked for 12-16 hours domU misses network.
No packets goes to dom0 vif interface (tcpdump says nothing).
xl dmesg says nothing.
qemu-dm says nothing
I'm try to rmmod xen_netfront module inside domU and after that
modprobe it and get errors:
net eth0: xennet_release_rx_bufs: fixme for copying receiver.
WARNING: g.e. still in use!
WARNING: leaking g.e. and page still in use!
ip a s says that i have eth0 but i cant get link up (ip link set up
dev eth0 says:
Cannot assign requested address)
This behaviour fixes reboot. But after some time this happened again.
P.S. I can check qemu-xen (upstream qemu) because it can't migrate
(see my previous emails with subject xen 4.3 test report.

What's your Dom0 kernel? Could you confirm netback is still running?
Did you try to rmmod xen-netfront when there was not connection? It
looks like the grant table entry is still in use. But if netfront was
still pushing packets to netback I think that warning message is
expected.

Not quite sure if this is related to QEMU. I think the preferred backend
is netback.

yes i'm try and after that domU can't manipulate eth0 interface (can't
assign address and up link)

Are you sure of this? The default is now qemu-xen and you don't appear
override it in your domain cfg. (although as discussed below qemu is
probably not relevant here)

Yes, I think the message is expected too.
I'm more concerned about the network dropping out after 12-16 hours
(which I think is what Vasiliy is really reporting).

Correct, nothing in the xen toolstack ever uses the qemu netback (which,
if it exists at all, is a xenner thing).
Since this is a PV g uest the only thing qemu will be doing is providing
the xenfb backend.

I'm sure - xm toolstack with xend con't operate with qemu-xen =).
And i use xm with xend because on 4.3 only this combination provide
live migration =)

I'm try to get more statistics with domU kernels that affected by this.
What can i get from my system to get more debug output in case of this error?

Right. I just wanted to know whether there was stale grant entry.
If, for some reason, netfront runs out of grant table entries I think
that might cause connectivity lost.
Vasiliy, can you grab more logs from DomU and Dom0?

Is about 36 hours in xen dmesg appeared messages:
(XEN) grant_table.c:289:d0 Increased maptrack size to 2 frames
(XEN) mm.c:1695:d0 Bad L1 flags 400000
Inside domU nothing. As i see network absent not only centos 6 kernel
based domU but on 2.6.32.26 (build from git jeremy xenlinux tree is
about 2 years old)

How about dom0 linux dmesg? Anything there?

If you didn't have more DomU up and running, this looks like a leak
somewhere.

And this... I have now idea at the moment.

Though that looks mostly like a backend problem, I would still ask if
you can spare some time to try the same workload on newer kernels and
see what happens.
And I would also need your Dom0 configuration, dmesg log in Dom0.

domains work's fine.

Bingo. On another server with this kernel and xen i have:
[131872.141036] vif vif-139-0 vif139.0: Too many frags
[131872.141042] vif139.0: fatal error; disabling device
What from dom0 configuration i need to provide?

Ah, this is a known issue. MAX_SKB_FRAGS in DomU is larger than the one
in Dom0, Dom0 thinks the packet is malicious and disconnect the vif.
Patches have been upstreamed to fix this, but the backporting to 3.8 is
not kicked off.
If you don't bother applying patches and rebuilding your kernel, you can
probably want until the backport happens.
If you cannot wait, look for email sent by Ian Campbell with title:
"xen-netback stable backports request (regression fixes)".
