I have a strange problem and apparently i am unable to solve it on my own. After hours of try & error i need your input.
i have a netctl network bridge:
$ cat /etc/netctl/bridge
Description="bridge"
Interface=br0
Connection=bridge
BindsToInterfaces=(eth0)
IP=static
Address='1.3.10.88/24'
Gateway='1.3.10.7'
DNSOptions=('resolv_conf_local_only=no')
DNS=('1.3.10.7')
## Ignore (R)STP and immediately activate the bridge
SkipForwardingDelay=yesthe interface is working as expected and my host has network connectivity
$ ifconfig br0

Thanks for the link. I had some issues with the latest bios updates on threadripper regarding kvm. I found, that compiling the kernel with CONFIG_CRYPTO_DEV_SP_PSP=n fixed that and the system is booting normally since then.
Seems i need to build the kernel linux-4.17.10 with CONFIG_CRYPTO_DEV_SP_PSP=n to have it working again - this is really a huge pain.
I am familiar with building a kernel on gentoo - i will give it a try on arch then.
EDIT:
i am back on linux-4.17.14 now and my win10 vm still does not receive an IP address.
EDIT2:
just stopped firewalld and networking works again
