can not recognize Ethernet card

today, I updated 'filesystem' to my VPS.
In order to update filesystem, I removed grub package, and forgot reinstall it after upgrade, then I cant startup the system.

Now I copied a backup 'boot/grub' directory to /boot,and reinstalled lastest linux-lts.pkg.xz in /var/cache/pacman/pkg, then I can startup my system,but here is my problem...

dmesg only show me this below:

#dmesg | grep -i ether
[ 11.741468] Initialising Xen virutal ethernet driver.
#ifconfig
lo: ..........
(and there is no eth0 stuffs ...)
#lspci
(shows nothing ....)

HOW CAN I GET MY ETHERNET CARD BACK TO WORK ?

Re: can not recognize Ethernet card

Does lspci really show nothing or does it just not show anything you believe to be relevant to the ethernet card.  These would lead to to different first suspicions.

Also, ifconfig does not list eth0, but as you've removed the rest of the output, we can't see what it does say.  Is there anything starting with enp...?

Aslo do the version numbers from `uname -a` and `pacman -Qi linux-lts` match?

Re: can not recognize Ethernet card

ifconfig not showing an interface is completely normal. Why do so many people think ifconfig will show them all interfaces? Serious question, because it's a very common phenomenon. As long as ifconfig has existed, it has only shown *active* interfaces, while 'ifconfig -a' shows all of them.
