Xen users - Jul 2008 - Another GPLPV pre-release 0.9.11-pre7

I''ve just uploaded 0.9.11-pre7. save/restore should be working for 32
bits on both SMP and UP, and maybe for 64 bits although it''s not
tested.
If someone could test migration it would be much appreciated.

The installer seems to not install the drivers under 64 bit
environment... but they can then be installed manually. Not sure why at
this point.

I confirm that the -pre7 drivers work under my usual test machine:

AMD Dual-Core AMD Opteron Processor 1220 stepping 03

with Ubuntu-server Hardy - Xen version 3.2.1-rc1-pre.

Tests (with apic=0):

* boot with /GPLPV: 		  ok
* boot without /GPLPV: 		  ok
* xm shutdown:			  ok
* xm save/restore:		  ok
* some exercises with BurnInTest: ok
* random disk activity:		  ok
* random net activity:		  ok

The only issue I notice for the moment is the "Safely remove Xen Net Device
Driver" icon in the tray area.

Regards,
Sandro

Tried this one with a fresh installation of windows 2003 Server German, SP2
Xen version 3.2.1
Intel C2D 6600 CPU

-Installation: No errors - ending with a lot of yellow "!" on the new 
devices
-Reboot with "/gplpv" - finding a lot of devices - telling me to
reboot
while showing me the content of the "new" disks - i do reboot.
-Filesystem errors cannot reboot - doing chkdisk /P /R in recovery-console - 
reparing errors - reboot
-bsod - SESSION3_INITIALIZATION_FAILED, STOP 0x0000006F(0xc0000130,0,0,0)
-starting without /gplpv leads to direct logout, when logging in.

May I have to do the first reboot without /gplpv ?

rebuild a backup of the vm for a new fresh start.
-installation -waiting short of the end 20 minutes - rebooting manual 
ignoring the last step of the installation
-rebooting, finding lots of devices, pressing a lot of "yes", all
devices
show "cannot start error 10", assuming the missing gplpv flag.
-rebooting again, all runs fine but yellow "!" on a lot of xen
devices.
-rebooting with gplpv, resulting in bsod as mentioned below
-rebooting without flag, runs again.

Is this a known error ?

I haven''t tried an install from scratch in the last couple of versions,
but no, I don''t know about that error.

What platform are you running on? Please specify hypervisor, dom0 and
domU if they are 32 or 64 bits.

Thanks

Hello James, and others

I''m rather new on this ML, and tested (performance) this drivers on
-Xen 3.2.1 (out of the box opensuse 11.0)
-Xen enterpise 3.1
and on both domU OS windows server 2003R3

tested performance with iperf RX and TX.
on both xen platforms i''d have to had to disable "Large Send
offload", if
not i didn''t came above 1Mbit/s with TX.

performance results with a test machine in same subnet, but beeing another 
physical machine:
Xen 3.2.1 (opensuse)
  RX: 0.0-60.0 sec  6.32 GBytes    905 Mbits/sec
  TX:                              314 Mbits/sec

Xen enterprise 3.2
  RX: 0.0-60.0 sec  3.46 GBytes    496 Mbits/sec
  TX: 0.0-60.0 sec    681 MBytes  95.2 Mbits/sec

for comparison on Xen enterprice with deleverd (commercial) PV driver:
  RX  0.0-60.0 sec  6.31 GBytes    904 Mbits/sec
  TX: 0.0-59.9 sec  2.78 GBytes    399 Mbits/sec

What is your physical NIC in your DomU? Do you know if it has support
for large send?

Was that with gplpv?

Did that have any pv drivers?

it''s a vlan interface on dom0, which is eth4:

# ethtool -k eth4
Offload parameters for eth4:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: on
udp fragmentation offload: off
generic segmentation offload: on

# ethtool -i eth4
driver: bnx2
version: 1.7.4
firmware-version: 1.9.6
bus-info: 0000:03:00.0

lspci -v:
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708
Gigabit Ethernet (rev 12)
        Subsystem: Hewlett-Packard Company NC373i Integrated
Multifunction Gigabit Server Adapter
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16
        Memory at f0000000 (64-bit, non-prefetchable) [size=32M]
        [virtual] Expansion ROM at d8500000 [disabled] [size=128K]
        Capabilities: [40] PCI-X non-bridge device
        Capabilities: [48] Power Management version 2
        Capabilities: [50] Vital Product Data <?>

Queue=0/0 Enable-
        Kernel driver in use: bnx2
        Kernel modules: bnx2


So it doesn''t have direct access to the nic, it''s the vlan
above it.

Yes, that''s with the gplpv drivers. 

so all tests are or with gplpv or with commercial pv driver.

I tested also opensuse 11.0 xen 3.2.1 with realtek emulation, but at
85Mbit/s RX i didn''t look any further.

Win2003 32bit migrations are unstable. Observed occasional BSOD (driver
errors) as execution started on the destination dom0.
