Hi there! I am currently setting up a Xen box on 3 VLans, each VLan interface is in a bridge and currently, dom0 is reachable from on of these and is performing great. My only problem is with domU : it can ping anything but it won''t work for TCP and UDP protocol UNLESS I do a manual tcpdump on my vlan interface. Bridges on dom0: xen-vl97 8000.001372529fbf no eth0.97 vif5.1 xenbr0 8000.feffffffffff no vif0.0 peth0 vif5.0 my domU has an interface in xen-vl97 which owns eth0.97. Only ping is working unless I do a tcpdump -i eth0.97 .... any clue? Thx in advance....

Hi again !!! The trick ''ethtool -K eth0 tx off'' in each domU solved my problem !!!! Thank you for your time.

Could you test in deep that you are not problem with UDP ?

[Xen-users] Sometimes the ssh or local console hang the terminal in DomU ...
Hello Sometimes when I open a ssh shell or using the local console a simple tail - f , top, cat hang the terminal ... The domU still runs only hang the terminal... Any ideas of what happens ?

AMD Turion 64 X2 Tl-50 1.6GHz Socket 1 Processor. Does this support hvm? Spec quotes DDR2 which I think implies hvm support. However, "socket 1" suggests otherwise.

Socket 1 is similar to AM2 except more compact to make it more suitable to the mobile/small-form-factor platforms that Turion is intended for. -- Mats> > Geoff Streeter >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

My only way to access one VM is using ssh, but sometimes I can''t get login using ssh (after type password, the terminal freeze)... Very strange... any idea?

Hi, What did you mean? I am supposed to get error with UDP packets? Also please note that I had to patch E1000 network card drivers to disable hardware VLAN filtering (VLANs were not working even with non-XEN drivers when HW filtering was enabled). The HW filtering will never give VLAN tagged packets to your OS, it will just drop them. I did not find a way to disable it on runtime but I read somewhere there a plans to do so in a future kernels/ethtool versions. The code is in e1000_main.c You will find this block somewhere near line 4369: /* enable VLAN receive filtering */ rctl = E1000_READ_REG(&adapter->hw, RCTL); rctl |= E1000_RCTL_VFE; rctl &= ~E1000_RCTL_CFIEN; E1000_WRITE_REG(&adapter->hw, RCTL, rctl); e1000_update_mng_vlan(adapter); Just comment it all and it will work great (especially for you my dear DELL PE1850 users ;) ) Have fun !
