Is there a way to determine what the hypervisor default NIC is? I'm using kvm/libvirt/qemu. If this is the wrong forum please please reply with that.

Thanks for letting me know I'm not making myself clear, let me try again with a few more specifics, These are Windows VMs with three disk images for C:, D: and L:. To simplify I'll focus on the image for C: which had grown to 77G physical size on the hypervisor's ssd (I just double-checked that with 'ls -al' because qemu-img below says 70G, this image had two snapshots at one

Is it possible to insert and eject a USB image in kvm/qemu/libvirt or are the only dynamically changeable devices cdroms and floppies? I've searched the web and I'm either not looking for the right terms or it's obscure. I should mention that I'm not talking about a connecting a physical host USB drive to a guest image, I want to be able to use a qcow image as the source.

I have numerous qcow2 images which need to be reduced in size and have their maximum size (virtual size) reduced. Physical disk space became so low that VMs "auto-paused" themselves, I moved enough images to solve the immediate problem but need to rectify the underlying issue. It seems that qcow[2] files are grown in size such that the data inside of them takes about 50-60% of the

Hi Leroy, How I can confirm that during rsync transfer corruption are not encountered? Thank you in advance.

I have had a single situation where corruption occurred during transfer (a few times, have no idea why),

Linux bind mounts can mount a file over another file (plus there's overlay filesystems), so it's possible to replace a binary even on a read-only device. -- Chris Adams <linux at cmadams.net>

Since you state that using -z is almost always a bad idea, could you provide the rationale for that?

I need to connect an older APS UPS unit to a machine running CentOS 7. Unfortunately the UPS only has a serial port whereas the computer does not. I am aware that there are USB-serial adapters but that the hardware or the drivers might fall short of expectations. Does anyone have positive experience with such an adapter? Or, conversely, would recommend avoid a particular adapter?

Does such exist? I looked for dante and couldn't find that. I found and tried using a version from CentOS 6 but it didn't work. If anyone can point me to an rpm (or set of same) I would most certainly appreciate it. Thanks.

You think this is irritating, what about when you're trying to replicate the network configuration to failover hardware... There is a way around this, I haven't tried it on CentOS but on Ubuntu there are kernel command line parameters: net.ifnames=1 biosdevname=0 which will override this behavior. Again, on Ubuntu these are added in /etc/default/grub as parameters to

Hi everyone, I have updated my backup server to CentOS 8.2. It runs bacula performing backup on disks. I would like to replicate backups on another offsite machine. I read about the ability to configure a new storage daemon in the offsite location and create a Migration/Copy Jobs. If I'm not wrong, it replicates only volumes but not replicate the catalog. I will try this. Another way to

USB to USB with standard USB cable will work. If one uses serial to USB adapter on the machine side (to create serial port through USB

Without context it's impossible to make firm statements but, having gone through this a while back (and discovering that less than 1 percent of an examined list of connections couldn't support current ssl - mainly Apple hardware), who do you want to protect? Is it the minority who won't/can't upgrade or the majority who have? And, do you have to protect yourself from liability
