PVE7 UP TO 8,network down

[edu-linux]

I setup pve 7.3.6 on my DELL R740(4216*2,128gb,gigabyte NIC*4, 82559 SFP+ 10G NIC) and works fine. upgrade to 7.4.17 first with apt,then change bulleye to bookworm on sourcelist. upgrade to 8.0.4.it still works well.but the kernel is 5.15.so I reboot the server and found kernel 6.2,but the network is down.

does anyone give some help? thanks!

ping 10.32.62.7 and 10.32.62.217 is ok,but ping gateway is not ok destination host unreachable
