can't start hvm with network

[Kevin Wang <kjw@xxxxxxxxxxxx>]

Installed ubuntu 24 onto E3-1225 v5 @ 3.30GHz (2C/4T) with one boring sata disk, but I can't get the vm to start the ubuntu24 server installer iso

cat >/etc/xen/auto/couch5.hvm <<'__EOF__'
builder = "hvm"
name = "couch5"
memory = "10240"
vcpus = 2
#vif = ['']
#vif = ['type=ioemu,model=e1000']
#vif = ['type=ioemu,model=rtl8139']
disk = ['phy:/dev/mapper/ubuntu--vg-couch--disk,hda,w','phy:/dev/mapper/ubuntu--
vg-couch--home,hdb,w','file:/d/dmg/ubuntu-24.04-live-server-amd64.iso,hdc:cdrom,
r']
#disk =
disk = ['phy:/dev/mapper/ubuntu--vg-couch--disk,hda,w','phy:/dev/mapper/ubuntu--
vg-couch--home,hdb,w']
vnc = 1
vncdisplay = 5901
boot="dc"
__EOF__

As depicted here, commenting out all the vif= lines, it does boot (but a server without a network isn't useful). But if I include any of the vif= lines, it won't even start, I get:

# xl create /etc/xen/auto/couch5.hvm

From a previous thread (which I haven't had a chance to try on that other 256GB ram machine), It was suggested that "big ram" vms may have trouble starting or start slowly, so I added:

echo 'GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=min:4096M,max:4096
M"' >>/etc/default/grub
grub-install /dev/sda

though I don't know how to prove that it had an effect;

# xl list

Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0 22019     4     r-----      32.5

Help?
