Unable to get dummy interfaces to persist across reboots in CentOS 8
Have you tried to use NetworkManager ?
After all ,anything network related should be done by it.

Unable to get dummy interfaces to persist across reboots in CentOS 8
No. Network Manager is always disabled on our builds since at least
Cent5 days. The network stack has always been able to be managed
properly without relying on Network Manager. Is that now an absolute
requirement? It never has been prior.

Unable to get dummy interfaces to persist across reboots in CentOS 8
Requirement is a very strong word , but you should consider using it and here is a short demo why:
- By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory.
[root at system ~]# ls -l /usr/sbin/ifup

Completely in despair - Xen and Windows domU
Hello!
I am using xen some years now and it just runs without any problems. But now one customer needs a stupid WinXP domU and I am trying to get this running for about two weeks...

Network problem: packets are lost in domU
Hello,
I am having big problems with Xen virtual network interfaces. First
I tried typical bridge support, no luck. The packets sent from dom0
to domU seemed to disappear somewhere. Then, to debug the problem
I have set up a simple point-to-point link and still have the same
problem.
I am using Xen 3.0.4-1 and Linux 2.6.16.x in both dom0 and domU.
I have tried kernel 2.6.16.35 and 2.6.16.41.

I have been running xen for a while now with two interfaces:

eth0 for the outside network.
my script looks like this: (/etc/xen/scripts/network-bridge-more)

Hash: SHA1
I have a linux system with 4 ethernet interfaces, eth0 goes to the internet,
eth1, eth2, and eth3 are NAT''d LANs.
I want to use an ingress filter to prioritize bandwidth
(downstream from internet) to various IPs.
I want to sett it up something like this....

[Bridge] aoe/vblade on "localhost"
hello !
i try to use a network technology on one single host, which wasn`t designed for that.
to give a short overview of what i`m talking about:
AoE is just like a "networked blockdevice" (just like nbd/enbd) - but without tcp/ip.
AoE kernel driver is the "client end" (see this like an iSCSI initiator) - and an etherblade storage appliance is the "server end"

Unable to get dummy interfaces to persist across reboots in CentOS 8
Anyone have any ideas? It's rather annoying that I can't get these to
persist across reboots without using some kind of helper script.

Unable to get dummy interfaces to persist across reboots in CentOS 8
Hello all, hoping someone can help me out here.
I cannot get dummy interfaces on a new Cent8 build to persist across reboots.
On Cent7 - this is the process I use:
Create Dummies:
# cat /etc/modules-load.d/dummy.conf
dummy
# cat /etc/modprobe.d/dummyopts.conf
options dummy numdummies=4
# ip link add dummy0 type dummy
## - repeating a/ ascending dummyN adapters for as many needed
# service

Flow Control and Port Mirroring Revisited
Hi,
Back in October I reported that I noticed a problem whereby flow control
breaks down when openvswitch is configured to mirror a port[1].
I have (finally) looked into this further and the problem appears to relate
to cloning of skbs, as Jesse Gross originally suspected.
More specifically, in do_execute_actions[2] the first n-1 times that an skb
needs to be transmitted it is cloned first and

dummy interface shenanigans - CentOS6
tl;dr - a renamed dummy interface is not persisting across reboots on Cent6.
I have a situation where I need to rename a dummy interface on my system.
I have a total of 3 dummy interfaces:

adummy0
I've been doing some puppet testing in a vbox VM to get this all
sorted out to deploy to a group of boxes. Every time I reboot my VM,
it comes up WITHOUT adummy0, but I notice

Xen from backports on sarge not working
Hi,
I've downloaded and installed the Xen packages from backports.org
in a box with sarge, and it doesn't work. That's the short story. Now the
long one :-)
The problem is that I can't bring up the domUs. This is the error
displayed when I try:

fw as filter broken?
Can someone verify that using fw as a filter in iproute2-2.6.11-050330 is
broken. Doesn''t seem to work in any case and I saw an earlier post that
would lead me to believe this is the case. If so does anyone have a
temporary fix?
Thanks,

Xen 3.2 Laptop Networking
Hello,
I am trying to setup the networking on a Xen Ubuntu
(Hardy) host on my laptop. I have the basic networking
working and guest is able to use the eth0/peth0
bridging mechanism to communicate to the world.
Is it possible to setup a dummy interface and bridge
in Xen 3.2, along the lines outlined in RedHat
