This is quite embarrassing, but I'm banging my head against a wall and
hoping other eyes will spot some obvious mistake.
I have an F31 guest (fedora30) running in QEMU/KVM on an F31 host
(Bree). I want to mount a host directory via NFS in the guest. I set
this up a long time ago and it has worked through several Fedora
releases without issue, but in a fit of spring cleaning I did a fresh
install of F31 rather than my usual update, so of course now it doesn't
work. Clearly I did something right back in the day and have now
forgotten what it was.
The guest can ping the host and ping the wider Internet, so basic
connectivity works (this is via a NAT-style connection). The host can
ssh into the guest.
Firewall setup on the host:
[poc@Bree ~]$ firewall-cmd --list-all
home (active)
target: default
icmp-block-inversion: no
interfaces: enp3s0
sources:
services: dhcp dhcpv6-client dns libvirt mdns mountd nfs nfs3 plex rpc-bind rsyncd samba samba-client ssh
ports:
protocols:
masquerade: no
forward-ports:
source-ports:
icmp-blocks:
rich rules:
And on the guest:
[poc@fedora30 ~]$ sudo firewall-cmd --list-all
home (active)
target: default
icmp-block-inversion: no
interfaces: enp1s0
sources:
services: dhcpv6-client mdns samba-client ssh

[poc@Bree ~]$ ping fedora30

Exports on the host:
[poc@Bree ~]$ sudo exportfs

But from the guest:
[poc@fedora30 ~]$ showmount -e bree
clnt_create: RPC: Unable to receive
What am I missing?
