similar to: set a different default gateway in an isolated network

Hello, I have a problem which is that some of my VMs are loosing there IP addresses from time to time. What I saw in the log is when this VM loose its IP address there are DHCPREQUEST send from the VM by dhclient and the server responded only 50 minutes later ! Any help, advise on how to debug would be welcome. Thanks in advance Patrick Here after is an extract from the log July 1st 2016,

Hello, I’m trying to set a default gateway on an isolated lan (because one of my VM get access to an other lan). I’m trying to use the option <route > but this doesn’t affect the default route on my VMs. Here is the network xml <network> <name>prd-private-lan</name> <uuid>2222222222222222222222</uuid> <bridge name='virbr3' stp='off'

I'm trying to migrate my VirtualBox test lab to KVM. In my VB configuration, I have several VM routers with 4 interfaces each. Each router has a bridged interface which connects them all together and to the outside world. I have servers/clients dispersed on each of the other private (Isolated) segments that use the routers as default gateways. In trying to make this work, I used Virtual

hello list, i cant create an isolated network with the virt-manager. installed version virt-manager 3.0.0 installed version libvirt 6.2.0 output in error-message: Error creating virtual network: internal error: Failed to apply firewall rules /sbin/iptables -w --table filter --insert LIBVIRT_INP --in-interface virbr3 --protocol tcp --destination-port 67 --jump ACCEPT: iptables: No

Hello, I have first a question (and then may be a problem), that I have difficulties to understand and eventually to investigate. On each of my guests VM, I see constantly a RX dropped number increasing , Even if the VM does nothing ! ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.100.15 netmask 255.255.255.0 broadcast 192.168.100.255

Currently, I have two networks configured via xml: virsh # net-dumpxml TestNetwork1 <network connections='2'> <name>TestNetwork1</name> <uuid>a76f665a-0196-4edb-81b4-340944a6869c</uuid> <forward dev='p1p1' mode='nat'> <nat> <port start='1024' end='65535'/> </nat> <interface

Lesson learned. I think I had the same IP address assigned to my VM router as I did the Host. Side question: where are the virtual networks stored when you create them w/VM Manager? -----Original Message----- From: Spanky Horawitz <shorawitz@gmail.com> Reply-to: shorawitz@gmail.com To: libvirt-users@redhat.com Subject: Isolated networks && test lab Date: Tue, 25 Aug 2015 17:17:56

Hi all, When creating a new network: 1) Is there a way to disable automatic spawning of dnsmasq on network creation? I read that leaving out the <DHCP> section should accomplish this, but that is not what I am seeing. 2) Is there a way to disable automatic installation of iptables rules? 3) For that matter, what is the purpose of the default iptables rule set? Doesn't

If the queue of xdp xmit is not an independent queue, then when the xdp xmit used all the desc, the xmit from the __dev_queue_xmit() may encounter the following error. net ens4: Unexpected TXQ (0) queue failure: -28 This patch adds a check whether sq is full in XDP Xmit. Thanks. Xuan Zhuo (2): virtio_net: separate the logic of checking whether sq is full virtio_net: add checking sq is full

Sorry for replying to this ancient thread. There was some remaining issue that I don't think the initial net_failover patch got addressed cleanly, see: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1815268 The renaming of 'eth0' to 'ens4' fails because the udev userspace was not specifically writtten for such kernel automatic enslavement. Specifically, if it is a bond

If the queue of xdp xmit is not an independent queue, then when the xdp xmit used all the desc, the xmit from the __dev_queue_xmit() may encounter the following error. net ens4: Unexpected TXQ (0) queue failure: -28 This patch adds a check whether sq is full in XDP Xmit. Thanks. v1: 1. rename to check_sq_full_and_disable 2. reorder some funcs to avoid declaration Xuan Zhuo (3):

Hi All, I am trying to migrate shares from my Win2k12 R2 AD server(SJCLAB2.LOCAL) to Ubuntu 16.04 samba fileserver present in same domain. Samba version is 4.3.11-Ubuntu. Before migrating shares I was able to successfully join fileserver to Active Directory. Below is my samba server configuration. #======================= Global Settings ======================= [global] workgroup =

Hai, As Rowland said also, your config looks better the we often see.. :-) I can only see one thing thats little off in bind is the auth-nxdomain. https://wiki.samba.org/index.php/Setting_up_a_BIND_DNS_Server Shows auth-nxdomain yes; You ADDC is the Authoritive DNS server for your domains so i suggest turn it on.

Hi! I am trying to get this scenario working: http://lists.xensource.com/archives/html/xen-users/2005-07/msg00558.html - Dom0 as well as the DomU firewall are Gentoo systems with Xen 3.0.2. - Both physical nics are hidden from Dom0 and are already working in the DomU firewall - A bridge exists in the DomU firewall (i don''t know if this is correct). That is for the DMZ to connect other
