[Xen-users] NFS DomU Client Performance

Hi All,

Quick question regarding NFS performance and Xen.

Have a series of Xen boxes running Xen 3.0.2 on FC5 with a stock FC5 Xen0/U
2.6.16 kernel. All things generally are great.

Was planning to deploy a couple of VMs for a couple of our software
developers so that they can test new software in relative safety, however I
am experiencing some poor performance issues with NFS.

NFSServer1 - Standard FC5 box (ie no Xen)
NFSServer2 - Xen based DomU FC5 box (exactly the same as above but runs as a
DomU)

DevClient1 - Standard FC5 box
DevClient2 - Xen DomU FC5 box

Basically, if I mount a NFS share from either NFSServers on DevClient2 it
takes a while to mount, but will eventually mount fine. If however I try to
mount a share on DevClient1 it mounts instantaneously. I have tested this on
a number of DomU boxes I have around for other services (LDAP/DNS/etc) with
similar results. Equally if I mount shares from a number of non-Xen boxes it
is again instantaneous.

Now I was expecting some overhead with Xen networking (as you''d expect)
but
this is a bit more that I was expecting. From my initial testing (admittedly
probably a little rough), a simple *mount nfsserver1:/mountpoint
/mnt/mountpoint* sits there for a good 90 seconds (although the end result
is it does mount), whereas a non Xen client mounts in under a second.

It doesn''t seem to make any difference whether the NFSServer is a Xen
or
non-Xen environment, the limiting factor always seems to be the Xen Client.

Initially I thought this maybe DNS issues, but this doesn''t seem to be
the
case. I have digged around and all is normal with correct results from any
machine. 

Any suggestions, is this a known problem, etc, etc??

TIA

I have no suggestions, but I would like to know if you''ve tried to see
what is different between the two ways to connect by using for example
tcpdump to see what the network traffic between the two machines look
like in the different cases. 

Also, what''s the configuration of your NFS server machine: What type of
processor, number of cores, amount of memory (Dom0 and DomU memory setup
in the Xen case). 

It may be that with this information, the problem can be solved quite
easile [but it may also be that it can''t - I haven''t played
with any of
the above parts, so I don''t know...]

[Xen-users] Blocked state in a DomU

Hi all!!

How can i change the blocked state to run state in a DomU?

Because when i said xm list show me these:

Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0     2781     4 r-----   652.4
mv01                               3      128     1 -b----    15.4
mv09                               5      128     3 -b----    16.8

The Domain-0 state is in run but the other two vm''s are in blocked
state

Somebody can help me?

Thx

If you do xm list, Dom0 will ALWAYS be running, since it''s the domain
actually performing the "xm list" command, and thus must be running
during this.

If you have more than one processor (any combination of hyperthreading,
dual core or multiple individual processors), you can ALSO have DomU''s
running at the same time, assuming that they are actually having
something useful to do [like calculations or some such]. 

Running state is ONLY valid on a Domain that is ACTIVELY running.
Blocked is the normal state for a domain that is waiting for Dom0 to
perform something on it''s behalf, or for a when the domain is waiting
for an IO device [if it''s got hardware access to IO devices directly].
Waiting for Dom0 is also the case when the Domain is waiting for
keyboard/mouse input, for example sitting at a shell-prompt. 

But unless you have more than one logical processor in the system,
you''ll never see anything but Dom0 in running state when you do xm
list,
as it HAS to run for xm list to happen...

Hi Mats,

Will try and answer as well as I can.

#TCPDUMP
Strange...

With a Xen client, I get seemingly standard traffic (bar a few checksum
errors) and then it seems to hang for 105seconds (I guess how long I seem to
wait) and then it carries on as normal.

With a *standard* client, it just works as normal.

I have added the logs below. (Not sure if this mail list takes attachments,
so these are just the Ethereal exported txt files. If it does can send the
TCPDUMP binary files if reqd.)
Both dumps are taken accessing the same DomU based NFS server (hence the Xen
MAC addresses in both instances)

#Specs
NFSServer 1 is a HP DL380. Dual 3.4Ghz EM64T (not dual core). Total RAM 4GB
NFSServer 2 is a HP DL380. Dual 3.4Ghz EM64T (not dual core). Total RAM 4GB.
1GB RAM setaside for DomU NFS Server. 1.5GB (other DomU''s, low yield
DHCP/DNS stuff), 1.5GB spare/used by Dom0.

DevClient1 is a HP DL380. Dual 3.4Ghz EM64T (not dual core). Total RAM 4GB
DevClient1 is a HP DL380. Dual 3.4Ghz EM64T (not dual core). Total RAM 4GB.
1GB RAM setaside for the DomU developer machine. No other DomU''s at
present,
hence 3GB RAM spare/used by Dom0.

All machines are pretty much identical. Are same revision hardware
(DL380G4''s), all use the embedded RAID circuitry and SCSI drives in a
RAID5
arrangement. Some are slightly bigger/smaller than others. All Xen boxes use
LVM based VBDs.

Makes no difference if I stipulate nfsvers=3, proto=tcp or aim my mount
towards an IP address rather than the FQDN. Whatever I try, it exhibits the
same symptoms. Different NFS servers (DomU or native), different clients
(DomU, native, FC4 & FC5) and different architectures (i386/x86_64, I tested
with another older DL380G3 we have surplus). All is the same apart from the
common thread of the client is a Xen DomU.

Very strange, especially as I don''t *seem* to be having any performance
problems with any other DomU network services, just NFS.

Thanks

Dan

Checksum errors... That may mean that the packet is discarded by the
recipient, which in turn means that it requires re-transmission by the
sender, which happens some arbitrary time later, say 105 seconds,
perhaps?

I''d like to suggest you search this mailing list for "checksum
offloading" to see if this helps your problem.

Sounds to me like a daemon (statd/lockd/rgcgidd etc) problem... I expect 
you are not running quite the same configuration in the domU, which
isn''t
suprising as some distributions don''t have standard NFS daemons and the
xen builds are not going to reproduce that. I expect the NFS daemon on the 
client is trying to talk to the local daemon which is missing, timing out, 
and continuing.

90 or 105 second delays are _not_ likely to be a XEN issue... although as 
Mats has pointed out, there can be checksum issues.

Try adding  "-o nolock,ro" to the mount command... if that goes
"way
faster", then you have a better idea of where the issue lies.

Re: [Xen-users] NFS DomU Client Performance

Hi Dan,

I suspect thats the old MTU/fragmenting problem.
Try to mount with option tcp (-o tcp).

As far as I recall, udp packets larger than (1500-something)
are transmitted in fragments and those are not reassembled 
correctly by xen.
You can track this down by setting rsize=,wsize= to lower
values,too. There is a limit somewhere at 14xx.

Surprisingly, nobody at xen''s seems to care about this...
 
Hope it helps,

Martin

RE: [Xen-users] NFS DomU Client Performance

Martin, Tom & Mats,

Apologies for the delays, was away at Reading Festival drinking beer and
listening to music :)

Thanks for the info, will have a bash and report in.

Thanks again

Dan

And the winner is Tom :)

That makes the mount instantaneous again. So I guess I do have a daemon
problem. After investigating, yes, it seems the client(s) I am having these
poor results on do not have a lockd process running.

So onto the crux...  How do I enable it???
