KVM High Availability Regardless of Storage - Gabriel Brascher, VP of Apache ...ShapeBlue
Having High Availability enabled for KVM Hosts can improve greatly the QoS by handling (fence/recover) a problematic Host as well as re-starting its stopped VMs on healthy hosts. However, there is a limitation on CloudStack HA for KVM; it relies mainly on NFS heartbeat script checks. This Talk illustrates how CloudStack HA works for KVM hosts and it presents a way of improving its implementation in a way that KVM HA works with any storage system pluggable on KVM, not just NFS.

가상머신을 구현하기 위하여 VMWARE, KVM, Hyper-V 기술들을 사용하였으나, 최근에는 Docker로 대표되는 LXC (Linux Containers) 와 같은 컨테이너형 가상화쪽으로 화제가 옮겨가고 있습니다.
컨테이너형 가상화 기술은 기존의 가상화 기술보다 가벼워 지고, 이식성이 뛰어난 특징을 가지고 있습니다.
최근에 컨테이너를 많이 사용하는 데에는 그럴 만한 이유가 있습니다. 컨테이너는 애플리케이션을 빠르게 제공하고, 다양한 배포 환경에 구애받지 않고 팀이 더욱 손쉽게 협업할 수 있기 때문입니다. 또한 효과적인 보안 솔루션 및 애플리케이션 통합 전략의 일부로 제공될 수 있습니다.

It hosted over 350 attendees, with 47 speakers holding technical talks, user stories, new features and integrations presentations and more.
In cloud computing environments, VMs require fast access to resources like storage and networking. The hardware that the VMs access is implemented in software and/or by passing through a dedicated hardware device. Software-based solutions consume extra CPU cycles, thus resulting in poor performance. Also, these require to expose a device-model to the guest, thus increasing the attack surface. Conversely, hardware passthrough provides better performance and security but can be expensive in terms of the number of physical resources, since each device is dedicated to a single VM. This talk focuses on how Vates is working on sharing hardware resources among VMs by relying on dedicated processors named Data Processing Units (DPU). More precisely, Vates work on offloading Xen hypervisor of storage emulation by relying on Kalray K200 DPU PCIe controllers, a hardware accelerator based on MPPA architecture.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

KVM the virtual router commands are timing out, resulting in MS shutting down the VR !
Snapshot failure ! In the logs it says that MS tried for ‘wait’ timeout.
Snapshot completes on Hypervisor after 6 hours, but MS logs show DB timeout
43. The Cloud Specialists
• The timeout can happen due to cloudstack aborting an operation
that is taking longer than expected.
• A timeout can also happen because one of the cloudstack
component failed to respond in time, like the agent or Hypervisor.
A timeout can happen due to external timeout conditions like a
database connection timeout or ssh script execution timeout.

Cloudstack Timeouts
Check the logs and try to determine what
kind of timeout it is ?
A timeout could point to problems with cloudstack subsystem
If it is a cloudstack timeout then tweak the corresponding
global timeout parameter value and restart cloudstack.

KVM the virtual router commands are timing out, resulting in MS shutting down the VR !

KVM Agent Timeouts
The timeout values changed in MS global config are not propagated to
KVM agents automatically.
Many times this result in failure to apply config to VR as the
aggregated commands timeout.
This timeout setting is governed by
router.aggregation.command.each.timeout global setting.
To make this or any other global setting effective on KVM agent you
need to add this to /etc/cloudstack/agent/agent.properties file.
We have a virtual router starting on KVM, after few seconds of start it is shutdown by
cloudstack.

4. Even though the action finished properly,
cloudstack rolled back the transaction on

Even though the snapshot operation succeed on Xenserver, cloudstack rolls back the transaction
on completion, thereby failing it.

wait_timeout” : the amount of seconds during inactivity that MySQL will wait before it will close
a connection on a non-interactive connection in seconds.

Service Offering
A service offering defines a set of virtual hardware features that will
be assigned to a virtual machine.
Storage Tags: These tags are associated with primary storage.
Host tags: Tags associated with hosts.

measure usage.

Compute and Disk Service Offering - Tags
This set of error has to do with pinning the virtual machine
to a particular set of resources.
You may want to do it to provide premium services to high
paying customers.
At some point you or your customer decides that the VM
needs to be moved to different set of resources.
What are the options at this point ?

“if our current compute offering is associated with tags (x,y) then the new compute offering

Instead create a new service offering and update the

KVM agent connection blowing up !
Xenserver snapshots failing as the chain is too long !
VMWare worker VM to create snapshots are not getting cleared up !
KVM the virtual router commands are timing out, resulting in MS shutting down the VR !
Xenserver have upgraded but it seems the existing xens are not instrumented with changes !
Some typical issues involving hypervisor
Cloudstack interacts with these hypervisors using agent framework.

Libvirtd log is at: /var/log/libvirt/libvirtd.log
Agent log is here: /var/log/cloudstack/agent/agent.log
For further debugging and querying you can use the virsh tool
virsh <command> <domain>
command can be vol-info, dumpxml etc
domain is the vm name like s-1-VM
virsh console s-1-VM
virsh dumpxml s-1-VM
There is a hypervisor (Qemu) and a management library (libvirt).
