similar to: how to make dhcrelay service use libvirt's interfaces?

hi everybody I'm looking at my setup and got stuck I have a box with two NICs on the same subnet, and another box similar, also two NICs on one subnet, all four NICs are on the same subnet. Now, that second box has also a virtual NIC (libvirtd's bridge route mode) and VMs guests are using it, traffic to that virtual net is routed via 1st real NIC. This second box dhcrelays to the

Okay. I may be missing something; from what you explicitly write about subnets, it sounds like you only have one, but if you don't have two subnets, why do you need a DHCP relay? SO. Assuming you have two subnets: * It sounds as if your DHCP request is generating an ACK. * I'm 99% sure your ACK has to traverse the DHCP helper and wend its way back to the originating host. So

Hello Every One! I need some advices with a problem i have. I''m working in a room from a department where the connection to the Internet is given by a NAT router and the IPs are given by a DHCP server. There are no firewall in the department so i''m trying to make a Firewall and a traffic shaper for all the PCs in my room. Because i don''t have access to the DHCP

Hi, I''m setting up a router (linux, debian-sarge), which shall relay dhcp requests from all subnets to a central DHCP server. The general stuff is solved, i.e. I can ping from any connected machine to any other including the NICs of the router itself. All firewall tables (including nat and mangle) are set to ACCEPT and flushed. On my model system I have the NIC 172.16.1.121 (eth1),

In our LAN a Linux-router connects 2 subnets. On this router dhcrelay is running. For several reasons we have to run a firewall on this box. But what is the right way to configure dhcrelay using Shorewall??? Thanks. -- Ad Koster <lidad@zeelandnet.nl>

Hy there, i have a centos (4.?) Box with nightly yum update enabled. Last night, it did an upgrade to 4.7 leading to several problem i.e. not respawning the dhcrelay, which is needed on this box. Can I control the update policy not to upgrade to new releases in the nightly updates? I would like do to nightly updates, but make release upgrades manual (I get a new kernel, so I have to reboot

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

Hi Ashish, IMO, it is yes, no way to increase tx_queue_size for direct type interface ------- Best Regards, Yalan Zhang IRC: yalzhang Internal phone: 8389413 On Thu, Oct 26, 2017 at 3:38 PM, Ashish Kurian <ashishbnv@gmail.com> wrote: > Hi Yalan, > > In the previous email you mentioned "tx_queue_size='512' will not work in > the guest with direct type

I'm running across the same weirdness mentioned in the "pxe weirdness" thread in the archives: http://syslinux.zytor.com/archives/2003-July/002229.html I couldn't find any followups to the issue. Was it a misconfiguration error? My setup is similar to James': I'm attempting to do a PXE install using DHCP sent via dhcrelay. I get the right IP, netmask, etc. but get

Hi Michal, What I found was that when I restarted the machine and did a virsh edit command to see the xml config, I see that it is was not actually changed. This suggests why I saw 256 again after restarting. So now I tried again to edit the xml via virsh edit command and used the following to set the parameters. <driver name='qemu' txmode='iothread' ioeventfd='on'

Hi there I set up a POC domain with multiple DCs, multiple remote sites and samba shares. This POC is a simulation of a whole samba3 domain migration. Users, and groups have been imported from the older domain to the new one. Here's the setup: ("Remote sites" are actually different subnets on the same location for the POC) *Main Site*: DC1 (RHEL7 - samba 4.6.4) DC2 (RHEL7 -

Logs from newly added node helped me in RCA of the issue. Info file on node 10.5.6.17 consist of an additional property "tier-enabled" which is not present in info file from other 3 nodes, hence when gluster peer probe call is made, in order to maintain consistency across the cluster cksum is compared. In this case as both files are different leading to different cksum, causing state in

Thanks, I discovered I had wrong permissions for /var/lib/libvirt/qemu/, after setting them to drwxr-x--x. qemu qemu and executing daemon-reload libvirtd.service exists now on my vms :) However - I'm not able to get it to run. In the journal I see the message libvirtd[6800]: Unable to import CA certificate list /etc/pki/vdsm/certs/cacert.pem I have verified its permissions and that it's

Thanks, Michal, On my laptop I do have libguestfs and libvirt-daemon-qemu. both libvirtd.service and libvirtd.socket are running ok on my laptop I just realized I haven't mentioned - my vms intend to serve as hosts themselves, and that's why they, too, need to have libvirtd.service running on them. up to recently I didn't have such a problem when I installed a vm on my laptop -

hi everybody I'd like to ask how libvirtd influences net.ipv4.conf.all.forwarding, would you know? I've noticed that if I use host's bridge, therefor there is no <forward mode= > in my network then "net.ipv4.conf.all.forwarding" goes back to 0. Is this intended I wonder? Looks like libvirt decides it's user responsibility now. many thanks

hi users I have my dhcpd to serve nothing but virbr0 (libvirt), OS is Centos 7.2 Dhcpd would not start, complaining like this: No subnet declaration for virbr0 (no IPv4 addresses). ** Ignoring requests on virbr0.  If this is not what    you want, please write a subnet declaration    in your dhcpd.conf file for the network segment    to which interface virbr0 is attached. ** ##SELECTION_END## and
