I wonder if there's a way to run a script upon every NetworkManager connection event. Topic starter wrote me that he bridged wired and wireless on Windows Server 2012 and it works for Hyper-V VM OOTB.

KVM virtio block layer - is TRIM/DISCARD supported?
Hi, One question please: If I use SSD as a storage on a host machine, does KVM's virtio I/O layer pass the TRIM/DISCARD commands to the SSD? I guess the question would be twofold: 1) is TRIM supported/forwarded if only one LVM'ed partition of SSD is forwarded? 2) is TRIM supported/forwarded if full SSD is forwarded (i.e. /dev/sdX) -- Best regards, Dmitry Mikhailov

OT: adding a wifi adapter to openvswitch
Hi all, Finally, I have installed openvswitch from source to two CentOS hosts: one 6.x and other 7.x. I will do some tests using openvswitch bridges to my KVM machines. One of these tests is to add a wlan0 adapter from comandline but only when this wlan0 is associated with a ssid without assign an IP. Is this posible? Do I nees to add some ebtables like, for example, Debian's wiki

OT: adding a wifi adapter to openvswitch
Actually I do a similar thing. I use a VM as my home/office firewall. It works quite well and I would argue it is as secure as your standard firewall based on something like openWRT running on dedicated hardware. I also run a wireless AP in bridged mode to allow local network access on an appliance. There should be no reason that you could not put both on the same physical hardware. As for

Using STP in kvm bridges

It's developed to provide loop-free redundancy links to Ethernet-based networks. I can't

If your laptop/server/smth is permanently wired to the internet, there's no problem to bridge this interface to the VM. But the topic starter wants to connect to the cable or wifi and still have a firewall VM. WiFi client connection with WPA(2) PSK encryption

CentOS 7.1 + KVM + OVMF for UEFI - can't reboot VM, only shutdown and start
Hi, I'm trying to use OVMF to run EFI-partitioned Windows 8.0 virtualized on my laptop. The reason is to reuse the original HDD image intact without re-installation of any kind. I'm running fully updated CentOS 7.1 (1503). Virtualized storage subsystem is VirtIO if it matters. I'm almost OK with the notable exception of inability to reboot the VM. OVMF bootloader doesn't

Xen and timekeeping
Hi everyone, I have the problem with Xen domU's and timekeeping in dom0. Time in dom0 was incorrect by 5 hours due to wrong timezone assumed. Fixed it by ntpdate ntp.nist.gov. The time on a dom0 was changed. I didn't append xen.independent_wallclock=1 to sysctl.conf thus the time in all domU's was also changed. But THEY DIDN'T "KNOW" THAT! The 'date' output

NFSroot over wifi in CentOS 7 - graceful shutdown problem
Hi, I've got a task to have a small number of laptops netboot Linux over WiFi. The kernel is loaded off the USB stick of cource, it's off topic for now. The WPA-supplicant daemon is started early by dracut off initrd. It works. Mostly. The problem is that upon shutdown systemd terminates all the processes FIRST and unmounts filesystems NEXT. Guess what? Upon termination,

new libvirt: CentOS 6.2 versus 6.0
Hi, About half a year ago I installed a stock CentOS 6.0/64bit onto an Intel server to virtualize our Linux fileserver and four WinXP boxes with rdp each. Since recent times I didn't do any upgrades of the server's OS. Now I have CentOS 6.2. After an upgrade I noticed that all virtual cpu name changed to QEMU Virtual CPU version (cpu64-rhel6) The new features were 1) The ability to
