Re: [Xen-users] New Win10 Home reliably crashes every other boot?!?
Oh, one other odd thing is that start-> reboot? That doesn't trigger this behavior. I can reboot like 10 times in a row and it works fine. Only xl create has this effect. Will experiment more tomorrow, thanks for the info - kjw

Can you replicate the crash after installing the Windows PV drivers?
https://www.xenproject.org/downloads/windows-pv-drivers/winpv-drivers-8/winpv-drivers-821.html
Other ideas:
- Juggle with vif type and model in the domU config
- Get rid of videoram and stdvga entries
If it helps here's a domU configuration template I'm using for Win10,
2012R2 and 2016 on various dom0 Xen versions (4.6.6, 4.8.3, 4.10.1), all
running on CentOS 6 and 7
builder = 'hvm'
memory = 3072
shadow_memory = '8'
cpu_weight = 256
name = 'win10'
vif = ['type=ioemu, bridge=br0, vifname=win10.0']
localtime = 1
acpi = 1
apic = 1
vnc = 1
vcpus = 2
vncdisplay = 1
vncconsole = 1
vnclisten = '0.0.0.0'
serial = 'pty'
disk = ['phy:/dev/vm/win10_img,hda,w']
boot = 'c'
sdl = 0
usb = 1
usbdevice = ['tablet']
