QUESTION
My goal is to connect two QEMU-KVM VMs on an overlay network. Each VM is running on a separate physical host and must have a static IP on the network 10.0.0.0/24. To achieve this goal, I want to use an OVS bridge with DPDK. I want to use the vhost-user-client protocol to connect the OVS bridge with the VMs.
My physical setup is the following: two physical machines equipped with a Mellanox ConnectX6-DX, and connected back-to-back (no physical switch). What I want to achieve is this:
...ANSWER
Answered 2022-Feb-12 at 16:38 suspect that the problem is related to the LINK_DOWN status of the vhost-client-1 port
[Answer] Yes, the cause for packet not reaching VM is OVS sees the interface down. Even with the presence of a rule to forward traffic from dpdk0 to vhost-client-1 the packets will be dropped.
The primary cause of link not up can be due to the qemu configuration memory backed with hugepages not being used. Vhost-USER port created by DPDK=OVS resides on the huge page memory area and access to the same is required.
A similar DPDK-QEMU StackOverflow address the use of viritio-client (via cmdline). So please adapt the settings shared into the link to virsh xml

QUESTION
I am first downloading a config file locally then I have to push that file into logstash server in the path - /etc/logstash/conf.d
...ANSWER
Answered 2022-Jan-27 at 17:10Adding to what @leandrojmp has already mentioned
The URI parameter you're using is of elasticsearch i.e. :9200(elasticsearch's port) which meant for sending the contents of a files over elasticsearch indexes as events(termed as documents in Elastic-stack's terminology) But based on the information you've provided, I assume you're trying to upload a config file to your logstash's server directory.

QUESTION
I am new to DPDK technology, so try to learn this new thing on my own.
I am running with 2 ubuntu vm i.e. vm-1 & vm-2 hosted on my laptop(windows-10).
I have configured each vm with DPDK enable pci.
Now on vm-1 ,I am running packetgen to send the pcap file towards vm-2.
On vm-2,I am running dpdk testpmd application.
Unfortunately nothing is receiving on vm-2.
I am using Following Setup:
Host Machine: Windows 10 Laptop Guest VM1 : Ubuntu 18.04 Guest VM2 : Ubuntu 18.04
Guest VM1 Running with pktgen-19.12.0 along with dpdk-stable-19.08.2 Guest VM2 Running With dpdk-stable-19.08.2
This is my 1st question to this forum so please accept my apologies.
...ANSWER
Answered 2022-Jan-25 at 04:31@Harish.malik setup consists of
- Windows laptop with VMWARE Player.
- Currently there are 2 instances of the Ubuntu as Guest OS.
- Each VM has 2 ports of e1000 (emulated) as default devices.
The reason for data traffic getting dropped is because the DPDK port (nic-2) were configured (as default settings). Isolating the NIC-2 on each into a separate Virtual Bridge solved the traffic RX-TX issue. Validated with Pkt-gen on both ends.

QUESTION
I'm building a WPF/MVVM application that displays some lists below each other. My MainViewModel contains in addition to the lists a textbox, whose text content I want to use as a filter for my lists. However, these lists are not in the MainViewModel, but in sub-controls (UserControl2_*).
If the filter property is in the same ViewModel as the ICollectionView, then filtering works (see CollectionViewFilter in ViewModel2.cs), but I don't understand how to apply a filter to multiple Sub-ViewModels.
Is there an MVVM compliant method to pass the filter through to the sub-controls? Or do I need to pass the collections up so that I can access them from the ViewModel, where the filter property is also set?
If there is any more code you want me to upload or adapt, let me know and I will edit my question.
...ANSWER
Answered 2022-Jan-04 at 15:01You'll have to link the CollectionViews and the filter method at some point, so your UserControl needs to allow that. I can think of three ways to do it:
Have your UserControl handle its own
CollectionView, and add a method to configure your filter (take aPredicate as parameter and set that to the Filter property).Have your UserControl expose a method which returns a
CollectionViewfor your list, and do everything in the MainWindow. Less pretty, but still probably alright, and avoids creating unnecessary stuff when you just want to display a list without any option.The most "MVVM" way to do it would be to add a
DependencyPropertyto your UserControl, with aPropertyChangedCallbackthat updates the filtering of objects. Then you can bind to a property of your mainwindow's viewmodel, and update that property based on your text field. Here's an example from some code i have :
QUESTION
I am using google's compute ssh command from compute engine's vm1 to connect another project's vm2. The problem occur when i try to connect with --command flag. The shell command is not executed but ssh connection is established. However i can see the bash command in the processes of vm2 as pid =xxxx 'bash -c sudo su && service nginx stop && source /home/x/bin/activate && python example.py' When i terminated the ssh command from vm1, the bash command immediately starts on vm2. I could not figure it out what cause this problem.
...ANSWER
Answered 2022-Jan-04 at 19:28That command set won't work. You're approaching it as if you were the one running the commands inside a terminal, in which case:
sudo su(would get you a root shell and all subsequent commands would run as root)service nginx stop(you're root)source /home/x/bin/activate(you're root)python example.py(you're root)
When you try to chain your commands with &&, it runs the next command after the first one worked and all the commands are actually being run as you:
sudo su(run as you, when this exits successfully, trigger next command)service nginx stop(as you)- etc (as you)
So what ends up happening is you get a root shell and then nothing. Unless that exits (cleanly), you won't run the next command in the chain and so you're waiting, because the root shell is also waiting. As @DazWilkin mentioned above, what you should actually be doing is removing the sudo su (you don't need a root shell, you can't do anything in there anyway) and preface your other commands with sudo instead so that they are each run with elevated perms.
QUESTION
We have two VMs behind a Load Balancer. We would like to make one of the VMs publicly inaccessible when we do a new deployment, so we can test the new version of the application before it becomes publicly accessible. The current plan is to block one out of two VMs by changing Network Security Group rule via Service Tag for Load Balancer:
It works. When we change NSG Rule for VM1 from Allow to Deny only VM2 stays publicly accessible. Once we verify that new release works as expected we then switch NSG rule for VM2 and switch NSG rule for VM1, so only a VM with the newest version of application is accessible while we update application on the other VM.
The problem with that is NSG rules don't immediately take effect and can take 1-3 minutes to make VM inaccessible/accessible. More over if we switch NSG for both VMs at the same time we can be in situations when both VMs with different version of software are publicly available which can lead to data corruption or data lose or both VM are not accessible. So the only way around this is to change NSG rule for VM2 then for VM1 and having downtime of 2-6 minutes. Is there a better way to do that?
...ANSWER
Answered 2021-Dec-29 at 11:04Blocking ports 80 and 443 with Windows Defender Firewall via PowerShell Remoting brought the downtime to 40 seconds total.
