Title:
5.15.0-58.64 breaks xen bridge networking (pvh domU)
Status in linux package in Ubuntu:
Incomplete
Bug description:
With 5.15.0-58.64-generic, bridge networking on xen is broken :
no packet (check with tcpdump) flowing between dom0 and any domUs attached
to a network bridge.
downgrading to 5.15.0-57-generic fix the issue. Thus the patch to the
netback driver seems the cause.
relevant network config :
brtctl show :
br0 8000.XXXXXXXXXXX no eno1
vif1.0
relevant domU config :
kernel = '/usr/lib/grub-xen/grub-i386-xen_pvh.bin'
type = 'pvh'
vif = [ 'ip=192.168.10.10 ,bridge=br0' ]
No message in dmesg, journal, xen logs..
