Centos 7 and qemu-kvm
Still trying to migrate to CentOS 7.
I used to use qemu-kvm on centos 6. tried to compile on
centos 7 and get error about undefined reference to timer_gettime
searching for that says basically use virt-manager
so I installed virt-manager - I have file images and those work.
some times I do directly to a USB connected disk.
I do not see how to do that in virt-manager ???

CyberPower usbhid-ups continuously disconnects/reconnect
I have had a similar problem to many other people for the last few
months with my Cyberpower UPS. It was working properly after reboot
about one in five times; the rest of the time it would endlessly
disconnect and reconnect, according to syslog messages.
The latest I was able to find towards a solution is

USB devices with same vendor:product id
Hi,
We have a VM with several USB devices attached. Everything works well, but sometimes, after a reboot of the host, some usb device get a different bus/device number and that prevent the reboot of the VM :
-------
error: Failed to start domain xxx
error: internal error: Did not find USB device 04b9:0300 bus:1 device:5
-------
I guess this is because we have multiple usb devices with the same

[EXTERNAL] Re: Tripp Lite SMART1500LCD repeatedly disconnecting and reconnecting
Thought I'd follow up in case someone else runs into this issue. In the end
what worked for me was tweaking the udev rules. I have had no USB
disconnects or stale data warnings so far. I only used one rule for my UPS:
# /etc/udev/rules.d/62-nut-usbups.rules
SUBSYSTEM!="usb", GOTO="nut-usbups_rules_end"
# TrippLite
# e.g. TrippLite SMART1500LCD - usbhid-ups

System Shutting Down Shortly After Boot, COMMBAD, "Writing Error", "Data Receiving Error"
I've been having a problem with my system during boot, which results in a
upsd/upsmon COMMBAD event shutting the system down shortly after it is
started. The shutdown is dependent upon the number of processes started at
boot time, and their load. Fewer processes and lighter load, and there is
no shutdown. More processes and heavy load cause upsd/upsmon to shut the
system down shortly after

[PATCH] virtio-blk: emit udev event when device is resized
When virtio-blk device is resized from host (using block_resize from QEMU) emit
KOBJ_CHANGE uevent to notify guest about such change. This allows user to have
custom udev rules which would take whatever action if such event occurs. As a
proof of concept I've created simple udev rule that automatically resize
filesystem on virtio-blk device.

Device 0 (vif) could not be connected. Hotplug scripts not working.
Hi,
I got this error when starting a domU on Centos 5.1 i386,
Device 0 (vif) could not be connected. Hotplug scripts not working.
Why is this happening ? I should restart the machine to see if this
still happends after a fresh network bridge. But it's somehow a
production server, I would like not to restart it, if possible. No domU
is currently running. I could start domUs a week ago.

USB devices - libgphoto2 - PTP - hplip
Hi All,
I'm trying to disable USB storage devices in Centos7.1.1503.
I've setup udev rules to block all usb devices and then additional rules
to allow specific vendors / products to be used (mainly keyboards and
mice). This is all working perfectly.
cat /etc/udev/rules.d/01-usblockdown.rules

Usb surf stick for internet
Hello,
I am searching for an internet usb surf-stick (umts) that works under
CentOS. Is anyone using such a stick and if so, which chip has this
usb-stick?
Would a Huawei E160E chip work under CentOS? Or maybe under CentOS with
the 2.6.35 kernel from elrepo?
Thank you very much!

Attaching usb devices
Is the only way to attach a usb device to a vm first specifying the device,
<hostdev mode='subsystem' type='usb' managed='no'>
<source>
<vendor id='0x3080'/>
<product id='0x1234'/>
</source>
</hostdev>
and then booting the vm while the device is attached? Can't I

Bug#705490: Uses deprecated RUN+="socket:"
Source: xen
Version: 4.1.4-2
Severity: important
Hi,
using RUN+="socket:" in udev rules files has been deprecated for a
while. In udev 183 support for that has been removed [1]
>From the NEWS file:
* udev: RUN+="socket:..." and udev_monitor_new_from_socket() is
no longer supported. udev_monitor_new_from_netlink()
needs to be used to subscribe to events.

Attach a GPS in preboot mode
Hello everyone and best wishes for 2023 :)
I have an old *Garmin Drive Smart 50 GPS* and I want to be able to
attach it when it is in preboot mode to a VM hosted by a *Debian 11 host*.
From what I understand, the preboot mode allows us to flash a firmware
before the GPS actually starts (used among other things when the GPS is
soft bricked).
When I connect the GPS to the host it gives:
