Hi Tomek,
Where are you uploading to? I have been having very
similar issues to you, however I've found that my issues are specific
to certain hosts on my network.
Do other DomU's on the same host get the same issues?
Cheers,
Steve

Hello,
I have a Win2k8 Server machine running on updated debian lenny, with installed GPLPV drivers. This virtual machine will be my company's file server, but.... Machine without GPLPV drivers have only 100MBit if's. This file server needs 1GBit interfaces. I also need ACPI shutdown from hypervisor option for shuting down vm for backups.
The wrong thing after installing GPLPV drivers is decreased machine upload. I could download about 40~60MB/s but upload runs at 10~20KB/s. It's to low for anything ;/
I've tested this behaviour with "Checksum Offload" enabled/disabled, "Check checksum on RX packets" enabled/disabled and combination of both options. None of that works.
For now I have no idea how to fix this.
This is config file of this vm:
kernel = "/usr/lib/xen-3.2-1/boot/hvmloader"
builder = 'hvm'
memory = 3072
name = 'fileserver'
vif = [ 'bridge=brXX' ]
disk = [
'phy:/dev/vgsas/dc1-sys,hda,w',
'file:/xen/ISO/win2k8.iso,hdb:cdrom,r',
]
device_model = '/usr/lib/xen-3.2-1/bin/qemu-dm'
acpi = 1
apic = 1
#pae = 1
usb = 1
usbdevice = 'tablet'
parallel = 'none'
serial = 'pty'
localtime = 1
cpus = "0,1"
vcpus = 2
sdl = 0
vfb = [ 'type=vnc,vnclisten=192.168.x.x,vncdisplay=1' ]
boot='c'
>
on_reboot = 'restart'
on_crash = 'restart'
keymap = 'pl'
Thanks for any advices.
