Meltdown requires a Xen fix (at a minimum), here's the current:
https://xenbits.xen.org/xsa/advisory-254.html

Spectre is a whole 'nother can of worms.  Not even really fixable in any robust 
way, it seems, but from what I gather reading this paper, it is very hard to 
exploit: https://xenbits.xen.org/xsa/advisory-254.html

[qubes-users] Re: Attach cd-rom block device to Fedora Template VM (where does it show up?)

2017-07-04 Thread Greg Strong 
Thanks, Andrew, I'm in business now.

The lsblk showed a new entry (xvdi) when the cd-rom was attached, but showed no 
mount point.  I didn't realize I needed to manually enter a command to mount it 
because I haven't had to do that with USB hard drives, but I guess this should 
have been obvious.

Anyway, in case anyone else has the question in the future and finds this 
thread, here's what you do to get a cd or dvd-rom to show up:

1. In a command prompt for the VM you wish to attach to, (before attaching the 
device), run 'lsblk' to list your block devices.

2. In the Qubes VM Manager, right-click on the vm you wish to attach to, select 
attach block devices, and pick your drive.

3. run the 'lsblk' command again and see what new device has appeared.

4. run the following command, substituting your device name for xvdi:

sudo mount -t iso9660 -o ro /dev/xvdi /mnt/removable/

Thanks again,
Greg

[qubes-users] Attach cd-rom block device to Fedora Template VM (where does it show up?)

2017-07-02 Thread Greg Strong 
Hello,

I think I'm doing something pretty basic and coming up empty.  I'm putting a CD 
Rom in an internal SATA cd-rom device and then using the "Attach block device" 
to attach it to a (running) Fedora template VM.  Where is this supposed to 
appear?  I can't find it anywhere.  /mnt/removable seems like a likely place 
but there's nothing there (although the Qubes VM Manager shows a device 
attached successfully.)

Doubt this matters, but this template is Fedora 2 - I followed the instructions 
to update the provided Fedora 23 template since Fedora 23 is end-of-life.  

Any help greatly appreciated.

Thanks,
Greg
