Cannot samba mount a remote windows disk
by Poh Yong Hwang 12 Apr '11

12 Apr '11

Hi, I would like to mount a remote windows disk as samba share drive but unable to do so on my host node. I tried it on my instances and it works so i am suspecting that perhaps firewall could be blocking it. Right now i see that the iptables for the host node with KVM installed : iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination Do i need to add anything to allow samba share to work? Thanks! yongsan

VMware Server 2 fails on 5.6
by Benjamin Franz 10 Apr '11

10 Apr '11

So others can avoid the lesson I learned this morning, VMware Server 2 stopped working after upgrading to 5.6 from a working 5.5 install (with the libc workaround for 5.4+ already in place). Some Google-Fu indicates the problem is linked to more supporting libraries being changed (zlib, libxml2, possibly others) in addition to the existing libc issue. I get a segmentation fault trying to launch VM Server 2 and have been unsuccessful so far in getting my install to work again. My own solution is I am rebuilding the physical hardware for KVM support and temporarily hosting the VMware VMs on a second machine I have still running 5.5 as I transition to KVM since it became apparent some time ago that VMware Server 2 is no longer a tenable platform. -- Benjamin Franz

Vlan trunk/QinQ connected to KVM guest
by Nataraj 04 Apr '11

I am running KVM guests under Redhat 6. I tried to setup a bridge device to an interface with a vlan trunk connected to a Juniper switch. On the KVM host, I am able to define vlans and access them via the vlan trunk. I was not able to access a vlan from the kvm guest connected to the bridged interface. I believe this would be what is commonly called QinQ or 802.1ad. Is this possible to do? I am using virtio drivers. If I can't do this, I guess I will end up with alot of bridged vlans. I tried doing this a while back under the vmware server and it did not work either. I think the reason that it did not work had something to do with arp resolution. I believe I read some where that it may be possible under ESXi. Thanks, Nataraj
