Re: [win-pv-devel] v9.0.0 released

[Steffan Cline <steffan@xxxxxxxxx>]

Well, as you can see it's been a few years since I replied to this email but 
I'm curious. 

Below is a sample configuration I based on what Paul recommended years ago and 
still works today with Xen 4.17 and qemu 7.2.0+h1-2

What I am curious of is, what options am I not using below that would better 
work with the most recent Xen drivers for Windows Server 2019+?

memory = 32768
maxmem = 32768
vcpus = 8
name = 'ec-win2016server'
vif = 
['ip=x.x.x.x,mac=00:16:3e:D5:07:xx,type=ioemu,model=e1000,bridge=xenbr0','ip=x.x.x.x,mac=00:16:3e:77:E9:xx,type=ioemu,model=e1000,bridge=xenbr1']
address = x.x.x.x'
netmask = '255.255.255.0'
disk = 
['phy:/dev/myvg/win2016server_img,hda,w','phy:/dev/myvg/win2016server_2_img,hdb,w']
boot = 'dc'
on_reboot = 'restart'
on_crash = 'restart'
builder = "hvm"
viridian = [ 'base', 'freq', 'time_ref_count', 'reference_tsc', 
'hcall_remote_tlb_flush', 'apic_assist' ] 
mmio_hole = 2048
vga="stdvga"
#stdvga=1 #test for higher resolution
#extra="vga=791"  #test for higher resolution
videoram=16
pae=1
nx=1
xen_platform_pci=1
usb=1
usbdevice=['tablet']
device_model_args=[ "-trace", "events=/root/events" ]
acpi=1
acpi_s3=0
acpi_s4=0
acpi_laptop_slate=1
vnc = 1
vnclisten = "0.0.0.0"
vncunused = 1
vncpasswd = "xxxxxx"


Thank you,

I don't think there's anything particular that you're missing but that 4k read 
number looks abnormally low compared to the other numbers, which I guess is due 
to the 8.3ms acc time. What version of Xen are you running on BTW?
