-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi all, I''m experiencing some problems on a domU with vlan and bonding. sometimes, tcp packets are retransmitted, and it issues with a lag of several seconds (4 to 10) on connexions (e.g. ssh) which makes it unusable... here is a small description of my stuff: one dom0 (debian 5.0.4 (amd64), xen-hypervisor 3.2.1-2) with 4 eth configured with bonding : eth0 and eth4 are enslaved in bond1, and eth1 and eth5 are enslaved in bond0. on bond1, I have a bridge with an IP address for dom0, and my domUs are "plugged" on my private network through it. on bond0, I have 2 VLANs bond0.90 and bond0.92, on each of them a bridge, with no address for domO. the domUs public addresses are "plugged" on those bridges. here is my /etc/network/interfaces on dom0 (one of public VLAN/bridge is not yet configured): auto lo iface lo inet loopback # The primary bonding interface : private network auto bond1 iface bond1 inet manual slaves eth0 eth4 auto brpriv iface brpriv inet static bridge-ports bond1 address 192.168.1.xxx netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 dns-nameservers 192.168.1.xxx dns-search my-domain.com bridge_stp on bridge_fd 0 # the bonding interfaces for VLANs (802.1q) auto bond0 iface bond0 inet manual slaves eth1 eth5 auto bond0.90 iface bond0.90 inet manual vlan_raw_device bond0 auto bond0.92 iface bond0.92 inet manual vlan_raw_device bond0 auto br92 iface br92 inet static bridge-ports bond0.92 address 999.999.999.999 netmask 255.255.255.000 network 999.999.999.000 broadcast 999.999.999.255 gateway 999.999.999.1 dns-nameservers 999.999.999.111 999.999.999.222 dns-search my-domain.com bridge_stp on bridge_fd 0 # end of /etc/network/interfaces here is my /etc/modprobe.d/bonding : alias bond0 bonding alias bond1 bonding options bonding max_bonds=2 mode=802.3ad miimon=100 lacp_rate=1 use_carrier=0 # end of /etc/modprobe.d/bonding I''m using the network-script dummy for setting domUs'' network, and vif-bridge for interfaces. my domUs are debian lennys (two 32 bits, and one 64 bits). with wireshark, I see at some time (seems to be random) retransmitted TCP packets, which cause my ssh connexion to lag, and a TCP out-of-order packet, and then everything comes back, until the next lag... these lags only appear on public network, through the public switch and the tagged VLAN (i.e. on private network, I don''t see any problem; when I ssh from one domU to another, I don''t see any problem either, nor when I ssh from dom0 to domU). any help would be greatly appreciated to know where exactly the problem is, and to solve. thanks at least for reading ;), regards, - -- Thomas van Oudenhove - PRES Université de Toulouse tél: (+33) 5 61 36 60 45 jabberID: thomasvo@im.apinc.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkuHobUACgkQSvC+RibfSOrZ5gCfaLr75x0SCfKAOIn98ndChSCT CXsAoOP3l+Muh6fP2L5MwHFXjsWbt6Ab =o2PP -----END PGP SIGNATURE----- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
