@jblaze I've been on Dropbox enterprise for one year... and now we are back to traditional SMB shares (latest SMB 3 with encryption etc, but still SMB).
For us it didn't work well. If you have a big amount of files (over 100Gb of active stuff), in my opinion it's not gonna work.
@aaronstuder said in Managing KVM via the Command Line:
Anyone have any good resources to learn to manage KVM via the Command Line?
Of course. The Red Hat Enterprise Linux Doc, section Virtualization.
Completely different stuff.
SAN is not for file sharing, in any way.
@jblaze said in Latency with VDI in VMware View 7 environment:
We're experiencing latency with our persistent VDIs in our VMware View environment. We're struggling with poor performance with our VDI desktops. Users are experiencing lag when dragging windows between multiple monitors, ‘choppy’ graphics/video, and slow application launching. The problems occur with local users. Both LAN and WAN could be involved. Also, file transfer times from the local desktop to the virtual desktop are super slow. Our bandwidth is dedicated 50Mbps up and down. Is there anything we can do?
Tipically, you will never be happy with that. The only environment I've ever seen where user were HAPPY with VDI was a dedicated LAN with a dedicate Dell m1000 with low per-node desktop density.

I can confirm it. We pay 600€/month for 10/10 dedicated FTTH. The only alternative is HDSL 8/8, that does not work well at all. Even a little rain used to increase copper latency tenfold.
Hi, it’s my business (also)! PM me if you are interested :).
This is IMHO the most interesting OSS project since many years to date, very nice work!
Can't wait to use the 1.2 in production.
@magicmarker said in Linux OS advice for building a SAM-SD:
I just want to mention that the KVM Hypervisor does take more than Linux basic knowledge. After @JaredBusch and @scottalanmiller recommended KVM on Fedora for the SAM-SD OS I have been playing with the KVM Hypervisor on a minimal Fedora install. I was able to successfully get a working KVM Hypervisor running. I realize that I've been very spoiled with the ESXi Hypervisor. I will require a more GUI based Hypervisor setup. I played around with the virt-manager which is a nice alternative to the cli for novice Linux users. There is still too much for me to learn with KVM and I never really did find instructions that really spell it out for me. I'm trying not to use VMware ESXi. I'm going to re-visit Hyper-V 2016 standalone with a Fedora Server (with desktop) VM to be my NFS file server. I'm open to any advice or words of encouragement to re-direct my focus back to the KVM Hypervisor.
Really? I've found KVM/libvirt much easier than XS/XAPI. KVM/libvirt has almost NO limits whatsoever, it can run and use any recent piece of hardware, any storage tecnology… any networking stack, of course.
Every time I reboot the host after the configuration of a local ISO SR (in a mounted filesystem, XFS) I got the "mantainance mode" in startup…
I've created the ISO SR with
xe sr-create type=iso device-config:legacy_mode=true
device-config:location=/path/to/mntpoint
and after that I mount the LVM logical volume (formatted in XFS) in /path/to/mntpoint, so I copied the appropriate row from /etc/mtab to /etc/fstab… standard procedure with Linux, really a mess with XS7!
The host would not start until I remove that row from /etc/fstab.
Is there a better way to mount the ISO SR in XS7 than doing it manually after startup?

@mlnews said in GoboLinux: Experimenting with a New Filesystem Hierarchy:
https://fosspost.org/2017/01/22/gobolinux-a-linux-distribution-with-new-filesystem-hierarchy/
There are many different Linux distributions out there. Thousands of them are designed to meet different purposes (no matter how small the difference from each one). Today, we would like to introduce GoboLinux for you.
GoboLinux is a special Linux distribution which is built from scratch. It offers an alternative filesystem hierarchy. To clarify this, we all know that the common Unix hierarchy includes directories like /usr, /bin, /etc.. But that’s not the case in GoboLinux. For example the filesystem directories here are:
- /System: The system files, binaries and kernel and placed here.
- /Programs: All programs are inserted in this directory. Each program has its own folder which contains its own settings, files and data. Multiple versions of the same program can be installed easily, because each version contains its own files sepearted from the other version.
- /Users: The home folders for the system users (root and all others) are listed here. It’s like /home in Unix hierarchy.
- /Data: The data folder contains information about packages and recipes needed by the system. It also includes the “Variable” folder. Which is actually /var.
- /Mount: Mounting directory if needed. Just like normal /mnt.
From the developers point of view1), this new hierarchy is a much better design for a filesystem. It keeps everything “categorized” which allows files to be preserved in these categories easily. To maintain the backwards compatibility with Unix hierarchy, a lot of symlinks are used to point to the directories on GoboLinux. For example if you run cd /etc it will take you to /System/Settings. Thus, there’s no need to modify the applications to work on the new way of categorizing these files......
I found traditional Unix hierarchy more confortable for interactive shell use, Mac os X is a pain with all that capital letters. Seems like a tribute to the "case sensitive".
@brandon220 completely wrong. Instead, use a couple of spinning rust for the Hypervisor and the SSD for the VMs.
I want to install XS7 in a server (Fujitsu) on which I just got the serial-over-lan access (no KVM in here, waste of money, I fully agree with that), but the XS7 installer automatically go into "GUI install" mode after the boot… no Grub or other bootloader menu are shown, and the start of the GUI automatically stop the data flow into the serial interface.
Is there a way to install XS7 in a completely GUI-less way? Thanks in advance!
@mlnews said in Using Unicode for Homograph Attacks:
It makes it nearly trivial to make it impossible to prove that a website is really the right website as there is no mechanism, short of human vision, to validate it.
I disagree with that.
A simple switch on the web browser config can force strict ASCII decoding and evidence the homography issue.
The feature it's already in place and should be the default from now on.
@stess no need to change a machine from 2012, if it's not broken. I still use a MBP late 2011 as my main machine and it works great… absolutsly no need to buy other hardware if he is going to learn development stuff.
If the laptop can run a Linux distro without melting, just use it and wipe Windows. It's 100 times better for development, especially for beginners.
I've heard that XS7 support thin provisioning storage also for local SR; does anyone know how to enable it?
By now, I stick to thick-LVM SR…
@Francesco-Provino said in iMac Pro:
Cannot find a purpose.
It's too pricey to be a graphic/video workstation, still lack performance vs the many multi-socket workstation/workstation, use AMD instead or Nvidia (CUDA!!!), non upgradable, non modular design with integrated display… any high-end workstation from Dell/HP/Supermicro can easily destroy it in any benchmark for a fraction of price, and with much better ROI, also.
So it's just like every other mac in that regard. Useless unless you buy into the "coolness".
I disagree. The macbook family (in baseline config) were and maybe are still great unix machines to work with. I had Dell XPS and other cool laptops, but with my macbook I had ZERO and I mean ZERO issue in six years. Still run like a charm.
Ok, Dell precision workstation maybe are even better and with great Linux support, but… guess what? They aren't that portable. The whole current XPS line is plagued with coil whine and other issues. The Thinkpad X1 is pricey and it's Lenovo… and maybe is the better alternatives. The mac just works, in my experience. I'm not a fanboy at all (apart about Linux :D), but I recognize good products when I use it… for years, without an hiccup.
@stess said in MacBook Air or Surface Pro 4 for beginning coding and casual use (youtube/facebook):
Thank you for all the replies.
I already upgrade his laptop with SSD, but the processor is just crap (IDK which one he had). His laptop is a low-end kind of laptop. He just want to kick things up a notch.
These two options were proposed by him. I do not have experience with neither, so I seek help from mangolassians.
The primary purpose for the air and surface would be casual use.
Why would surface Pro a bad option?Some of you asked how did these two become the top choices? He wants something light that wouldn't feel like carrying a brick in his bag. If you have other suggestions please let me know.
I've returned the Surface 4 last month, and I also made a review of it in my blog. Is not. That bad, but… you can buy better hardware for the same money.
Consider some Thinkpad or Dell business line, they are usually a good investment.
Ok, using the ext type of storage the thin provisioning works without an issue; thanks to everybody for the answers!
