Re: Cad package move to 6.9

[Francesco M. Taurino]

Hi, if you only require 2d cad, take a look to draftsight, from dassault
systemes. I don't know if new versions run on so 6.x, but it's basically
free and worth a try.

Re: What is the best way to start a KVM VM at boot?

[Francesco M. Taurino]

you should install acpid in your guests. this daemon will start shutdown
procedure in guest when you send shutdown command via kvm cli
or gui clients.

Hi Steve,

Is that the same thing as the check-e-do box in the virt manager
of the vm under boot options?

You can choose to shut down rather than suspend the VM at
shutdown by changing the settings of libvirt-quests.


quests or guests?  Was that a typo?  (Typos???  I never make typos.
What ?!?!?   Okay, okay, maybe 2 or 3 hundred every so often.)

Not finding how to alter libvirt-guests.

Also, I sent the "shutdown" command from the console and
the vm ignored me.  Does this mean I should stay with "suspend"?

Hi Francesco,

I am not seeing that as an option in the kvm console.  Am
I missing something?

Re: VMware

[Francesco M. Taurino]

hi,

yes, the wlan card seems fully connected.

in virtualbox 4 or 5, when you create a virtual machine,
in the network settings panel, select the bridge mode and
the physical nic you want to use, like in this screenshot:

http://i.imgur.com/FYr4BZs.png

(in italian, but clear I hope...)

it works even in open source edition of virtualbox and if the
host is connected to a wpa2 enterprise secured wifi network.

have a nice day,

Hi Francesco,

I just installed VirtualBox-5.0-5.0.6_103037_el7-1.x86_64.rpm along 
with Oracle_VM_VirtualBox_Extension_Pack-5.0.6-103037.vbox-extpack

and the MS Win tools package of the above VirtualBox release to no avail.

What do you mean by "wifi adapter must be fully connected on your 
linux host"?


On the SL7 host, ifconfig -a shows:

wlp61s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
inet 192.168.[redacted]  netmask 255.255.255.0  broadcast 
192.168.[redacted]

inet6 [redacted]  prefixlen 64  scopeid 0x20
ether [redacted]  txqueuelen 1000  (Ethernet)
RX packets 45054  bytes 47174187 (44.9 MiB)

TX packets 28494  bytes 3464767 (3.3 MiB)
TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

with the above redacted just in the event of any attempted compromises 
from any inappropriate use of this public list
(not by any legitimate subscribers).  However, all of the redacted 
data is valid and wlp61s0 is fully functional.


Is this "fully connected"?

As for KVM, I have other reservations about this on a workstation (not 
hardened server with external firewall defense) -- but that is a separate

subject.

hi yasha,

kvm windows 7/8/10 guests can be a bit slow in graphic applications,

if you need cpu/memory raw power.

you can use virtualbox, and bridge the virtual lan card of your guest 
to a physical lan
or a wifi adapter. the wifi adapter must be fully connected on your 
linux host.

vbox has, but this can be remedied by compiling/turning on the 9pFS

Re: What library is needed to have X11 borders?

[Francesco M. Taurino]

Install x2go server, icewm or openbox and a simple xterminal. With this
stack   your gui apps will be usable even on slow networks.

 Greetings,

 I have a SL6.6 server I built for a specific application. 99% of this
 app is command line, however, one specific aspect of this app requires a
 gui to use.

 When I built this server I wanted it as lean as possible so I built it
 with a minimal server install. Because the app acts funny when X
 forwarded over SSH, I tossed on a vnc server and a wrapper script to
 auto-start the app. It works!

 The issue is that the app pops up in a tiny window and you can't move it
 or scale it or anything else I tried. :-(

 Well, I know why. X11 doesn't have a proper windowing manager which is
 usually responsible for window borders. X11 is just the frame work. The
 question is, how do I get borders without installing a full desktop?

 I tried installing the group package x11 but that didn't help.
 I tried matchbox, but that didn't work.
 I tried installing the group package for the Ice Desktop, but that
 didn't help.

 I tried installing as little of Gnome as I could without installing a
 bunch of junk like pulseaudio and NetworkManager (Both are great on my
 laptop...but not on this server), and that just added a ton of clutter
 and still didn't work.

 I spent an hour bumming around on the Internet installing every package
 I could find recommended and I still can't get borders around the
 application.

 I know it isn't my script or my app. If I run the script/app on a system
 with a full gnome install, it works. I just don't want a full Gnome (or
 any major desktop) install on this server.

 Can anyone help me figure out which package I need?

 Thanks!
