similar to: Libvirt and iptables rule order

Hi, If I issue the commands # service libvirtd stop # service iptables stop # service iptables start # service libvirtd start the iptables rules that enable NAT on my virtual networks are not created when libvirtd is started, even though the networks are set to autostart and 'virsh net-list' shows them as active. The rules are only created if I run net-destroy and net-start. Is this

Hi, Following the directions for setting up bridged networking in the red hat virtualization guide and libvirt wiki, I set the following kernel parameters to 0 on a RHEL 5.5 server. net.bridge.bridge-nf-call-ip6tables net.bridge.bridge-nf-call-iptables net.bridge.bridge-nf-call-arptables Unfortunately, doing this broke the port forwarding I'd set up for VMs on my NAT networks, e.g.

Hi, I have a puppet module that I''m using to manage Oracle 11G. I''m using puppet 0.24.8 on 64-bit CentOS 5.4. Everything works properly except the execution of the oracle installer. It fails because it believes that the user it is running as is not a member of the proper groups. However, the user is in the groups, and if I log in as that user and run the same command that puppet

Hi all, I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights. I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set: virsh # net-dumpxml nat_limit <network> <name>nat_limit</name>

I know this is OT, but I'm not sure where else to ask. I can hope for fogiveness! :) My home router sends its logs to the rsyslog on my desktop system, and from there I can learn all kinds of interesting (or disturbing) things. I've written a really horrid shellscript (about 20 things piped together with a temp file in the middle) to give me the count of DROP events for specific incoming

Correct me if wrong, but I was under the impression that the processing required for playback was totally independent on the level of compression. The encoder looks for polynomials that fit, and it takes much more processing to find polynomials with a very good fit and small residuals. On the other hand, the decoder just has to multiply out the stored prediction, which is independent of the

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

My friend somehow managed to get a BDP-95, even though the hardware isn't scheduled to ship until March. The problem is that the manual makes no mention of FLAC, at all, and only the web page claims to support the format. Playback of flac seems to work, but files from one online vendor work flawlessly while files from other online vendors have strange glitches that sound like a

Hi All, I am a newbie to libvirt. I am trying to set up a Lxc container using a nat based network. I am able to create the container and log into it. But I don't see any interface created by default in the container. In other words my ifconfig inside the container does not show up any interfaces even if I run 'ifconfig lo up' for a loop back interface. Also I don't have any dhcp

Hi everyone. Those are the iptables forwarding rules associated with the two virtual networks on my machine: ----------------------------------------------------------------------------------------- -A FORWARD -d 192.168.100.0/24 -o virbr1 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.100.0/24 -i virbr1 -j ACCEPT -A FORWARD -i virbr1 -o virbr1 -j ACCEPT -A FORWARD -o

OK I rebooted. I changed the NIC from Bridge to Passthrough, hit apply, then changed it to bridge and hit apply, then booted the VM. My firewall looks better but still not working. iptables -L FORWARD -v -n | egrep '(policy|virbr1)' Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) 0 0 ACCEPT all -- eth0 virbr1 0.0.0.0/0 192.168.100.0/24 ctstate RELATED,ESTABLISHED

Version 1.2.1 introduced new rice coding techniques that are used by the reference encoder for 24 bit files. An older version of the decoder will have trouble with frames that use this encoding...
