Virsh console not responding after rebooting guest machine
us flag

I have a server running Ubuntu 20.04 with KVM. Whenever I install a guest VM (CentOS 7 or Fedora 34), virsh console works fine in the beginning. However, when I reboot this VM, virsh console stops working.

Does anybody know what's going wrong in this case?

How to deal with AD when deploy Hyper-V cluster?
us flag

I try to plan Hyper-V cluster deployment over several host servers (10 or maybe 12; hosts are rented) placed in two separate datacenters. This will be Hyper-V Server 2019 Core hosts. The problem is, I don't know if I should rely on AD for host auth, and if not, then what's the best way to maintain the cluster.

The main idea was to create Hyper-V cluster that's not connected to office AD servers s ...

Encrypted files stored next to GPG Key in backup – alternative solution?
nl flag

During a recent test run to see if my personal backups work as intended, I noticed that I store my GPG key next to files encrypted with that key on the same disk. Although the disk is encrypted (LUKS) and the key has a strong passphrase, this feels a bit wonky.

While having a second drive just for the key might improve the situation, it also feels a bit overkill. Hence I am looking for a more pra ...

Expanding RAID volume on PowerEdge

I have a PowerEdge T620 and R620 with RAID5 volumes on Perc H710P controllers. Can these be expanded in place with no data loss by adding additional drives?

I have seen this demonstrated online, but it's not an option in the RAID management interface (Ctrl-R upon boot). All firmware is up-to-date, but I don't have a copy of OpenManage installed if that matters.

This is trivial on Synology NAS units, ...

how openshift service loadbalance between pods?

This is a pretty basic question so I figure I must be missing something obvious, Does openshift service uses round-robin to load balance between pods? Or does it forward requests to the pod with the greatest amount of available resources? Or is it totally random?

My service configuration looks like that:

kind: service

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
