Of course, you can incrementally add multiple virtual disks to the VM, adding it as PV to your VG etc…

RE: Fedora Block Device Full How - Extend Partition
I see you are using LVM (that's good!), so…
- First, create a new block device in the free space;
- PVadd the new block device to your VG (fedora, I think);
- lvextend your root LV;
- xfs_growfs your root FS, and you'll be done ;).

CentOS is also the Dom0 of XenServer. So you get great overlap there for people using that.
yet the XO guys are using Ubuntu instead of CentOS
Ubuntu's kool-aid is hard to resist.
It's marketed to non-IT and/or non-Linux people heavily, which is part of what makes it bad for Linux people.... so much of how it is used and why people use it is bad.
It's marketed heavily to them but a lot of devs use it too.
They do a lot of interesting things. Juju, MaaS, LXD, Landscape, etc. Things that are really useful that no one else has.
I agree with you, LXD is a big big thing. There are valid alternatives to Juju. With LXD and Juju I can do an LXD-based full OpenStack deployment on my LAPTOP. 13 Containers and 16 Gb of ram… it works and is decently fast.
CentOS is the gold standard, but Ubuntu has gained really A LOT of traction in the last year. I was one of the anti-ubuntu guy before the 16.04.

RE: KVM Guests Backup - CentOS7
@aaronstuder said in KVM Guests Backup - CentOS7:
@Francesco-Provino What about puppet, anisble, etc?
I've tried to get puppet working several times, but never get right. Over-complicated, and I dislike the DSL language.
Salt is simpler and easier, and better than Ansible IMHO. I don't like the Ansible push-mode, is slow and tracking issues is hard. -

RE: KVM Guests Backup - CentOS7
@aaronstuder I strongly suggest you to use the same software you use for phisical machines, an agent-based backup software.
I heard that there is something by acronis for full-vm backp, but is not that widespread.
Trust me, every method that you can find on the net use a combination of qcow or lvm snapshot… and they both aren't good for serios backup.
Snapshot in qcow are not ok because you must retain all the snapshot chain on the backup storage AND on your main storage, and you can't do the merge of the oldest ones. Performance wise, they are also not as good as LVM.LVM snapshot are weird if you want to export it in another storage.
Maybe the best solution is to take full backup of the VMs every month, and use the agent-based backup for files, db etc.
Big installation (where KVM shine!) don't use angentless backup, they just rely on their infrastructure-as-code toolchain to rebuild the environmente and on agent-based backup for data.

@stacksofplates I don't think anything you wrote about KVM is true, and it never was true also. I don't think I'm biased towards KVM in any way, I use more vSphere and XS hosts than KVM ones as of today, but… KVM and the standard toolstack has everything. At least, anything apart from some very new and particular GPU or latency-related stuff that only ESXi and customized (AWS!) Xen have. But of course, the basic and advanced stuff are absolutely covered. Every single thing.
He's talking about Boxes, not KVM.
Oh, ok, now it makes sense! Never heard about Boxes… libvirt is really anything you need for KVM. Maybe virt-manager, if you are used to XenCenter-like administration…
Boxes is a VERY nascent KVM front end. I'm playing with it right now, it's neat that it uses KVM with local console redirect. But it needs some polishing, the interface is awkward and missing a lot of basic features.
Why use Boxes when virt-manager and virsh are mature and already in place?

@scottalanmiller Have you used boxes? Very impressive.....
No, I looked at it very briefly and it seemed a little neat but there was something that it didn't do and it just didn't have anything that I wanted. I use VirtualBox when I need VMs on Linux.
Why use VirtualBox when you have the much more capable and performant KVM included in any distribution?

Very similar to what I use, other than XAPI and various RDP clients.
I also like Midnight Commander and ZSH instead of FISH. -

The ThinkPads generally have Ethernet, great reliability, great keyboard (+ clit mouse) and external battery (love that!).
The Thinkpads are Lenovo now right? General consensus around here is to avoid Lenovo.
I know about the malware stuff, but ThinkPads were unaffected and I'm sure Lenovo has the will to rebuild a sane reputation...

RE: New laptop
I've just returned a Surface and I'm about to take an XPS 13 or a ThinkPad (T470, X1 or X270), mainly for Linux compatibility.
The XPS has a great display and is very thin and light, albeit powerful.
The ThinkPads generally have Ethernet, great reliability, great keyboard (+ clit mouse) and external battery (love that!). -
RE: Mixing Linux & Windows Server in a SMB
@cggart said in Mixing Linux & Windows Server in a SMB:
@scottalanmiller I see so we are stuck with Windows then anyways. Intresting point you made about the VPN. I've worked some other small business and that is how support was administered. Now that I think about it it does give access to the entire network where the other options you listed limit it only to where it is needed. I suppose that's obvious just didn't occur to me for some reason.
I'm using ZeroTier (no bridging!) to get to the bastion hosts of the systems I manage. Very recommended, It's easy to use and IMHO much more secure and simple than obscure NAT forwarding through many routers etc.
-
RE: ZeroTier - are you using it in production?
@Dashrender I've deployed it to only the jump hosts in four company, in about half of the machines in my company and almost every machine in my home lab and other AWS instances. I don't use DNS with ZT, because the IP is static and is always the same, no matter from where I connect.
-
RE: ZeroTier - are you using it in production?
I'm using it to connect my laptop to various jump hosts. Other than that, I'm testing it against openvpn to connect a remote office to an ERP. I use the free plan, it's enough for now and works very well.

OpenVPN DNS issue under Linux
I got several OpenVPN servers and they works perfect with Mac and Windows client, either the DNS push. I cannot understand why, in Linux, the DNS server address is pushed into resolv.conf, but almost nothing works. I can resolve the hostname using the "host myhost.mydomain" command, but every other tool failed the resolution (E.G. ping) as if they are still using the old address.
Any idea about this strange behaviour? Is there something that I'm missing? -
RE: The Sysadmin / CTO machine - A Surface + Cloud to rule them all?
The last question for you all… I'm going to get a Dell XPS 9360, but I cannot decide between regolar FHQ and touch QHD screen…
FHD
- more battery life
- more compatibility with standard Linux GUI
- little cheaper, little lighter
QHD
- more brightness
- a lot more pixel
- touch capability
