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



It's been a while since I replied on this since I've had lots of testing going 
on.

I just ran these tests on a new install of Win Server 2019 fully updated with 
all of the 9.0.0 drivers. 

My config is this:
memory = 16384
maxmem = 16384
vcpus = 4
name = 'ec-win2019-1'
vif = [ 'ip=x.x.x.x,mac=00:16:3e:CD:0B:01,type=ioemu,model=e1000,bridge=xenbr0' 
]
address = 'x.x.x.x'
netmask = '255.255.255.0'
disk = 
['phy:/dev/vg_san/ec-win2019-1_img,hda,w','file:/root/en_windows_server_2019_x64_dvd_4cb967d8.iso,hdc:cdrom,r']
boot = 'dc'
on_reboot = 'restart'
on_crash = 'restart'
vnc = 1
vnclisten = "0.0.0.0"
vncunused = 1
vncpasswd = "kldwslex"
builder = "hvm"
viridian = [ 'base', 'freq', 'time_ref_count', 'reference_tsc', 
'hcall_remote_tlb_flush', 'apic_assist' ] 
mmio_hole = 2048
vga="stdvga"
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


The VM is running on a Dell R620 2x10core 3ghz w/384gb. The drive is actually 
over an 8gb FC to a R720 with SCST running as a SAN w/ Raid-6 and 12x3tb drives.

Since this works so well, I'm guessing the previous issues reported may have 
been due to the config I had since merging your sample config with what I had 
seems to work fine. That same VM I originally tested with now has the 8.2.2 
drivers back on it but with the latest Xen kernel I have, it just power cycles 
over and over. I had to move it to another server running an older kernel. I'll 
have to figure that out.

I did some disk i/o tests and am curious if the attached results look 
appropriate for the environment or if there's some tuning I'm missing.

Any suggestions are appreciated.

 
Thank you,

    Can someone post a log of the qemu output (with xen_platform_log in the 
events file) so we can see what the PV drivers are doing?
    
    I generally do most of my testing against the latest Xen (i.e. 4.13). 4.8 
should be fine though; the main differences from a Windoows PoV would be in the 
viridian enlightenment code, but that's orthogonal to the PV driver interfaces.
    
    I've trimmed out the cruft from the config I normally used and attached it. 
(I also normally boot Xen with a grant frame limit of 128, i.e. 4x the default).
