HI, i have been getting a issue about xenserver and debian based distros vms. What happens is when debian vm try get ip from dhcp , it can''t get any ip address and syslog says: Aug 8 17:59:36 debian dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3 Aug 8 17:59:36 debian dhclient: 5 bad udp checksums in 5 packets I found the documented issue http://www.mail-archive.com/kvm@vger.kernel.org/msg41958.html talking about dhclient. Now, the only way to get ip address is running dhcp server in other host, however vm and dhcp vm can''t stay in same host. Anyone know about it? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
You need to turn off TX checksuming in DomU. apt-get install ethtool In /etc/network/interfaces: # The primary network interface auto eth0 iface eth0 inet dhcp post-up ethtool -K eth0 tx off HTH Christian Am 08.08.2011 um 23:09 schrieb Diego Spinola Castro:> HI, i have been getting a issue about xenserver and debian based distros vms. > What happens is when debian vm try get ip from dhcp , it can''t get any ip address and syslog says: > > Aug 8 17:59:36 debian dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3 > Aug 8 17:59:36 debian dhclient: 5 bad udp checksums in 5 packets > > > I found the documented issue http://www.mail-archive.com/kvm@vger.kernel.org/msg41958.html talking about dhclient. > > Now, the only way to get ip address is running dhcp server in other host, however vm and dhcp vm can''t stay in same host. > > > Anyone know about it? > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
