similar to: Windows Xen VM's have high guest CPU usage and poor performance

Hello, Is it possible to get the name that was set in a VM's xen config file from the guest machine? I'm interested in having my kickstart launch a script that can configure hostname, but to do that it would need to get the name set in the config. Thanks, Ryan

I found on some CPUs an ACPI based HVM chews up a lot of CPU time versuses an APIC HVM, so in Windows I would change the computer type in device manager to "Standard PC" and disable acpi in the domain config. -Ross ----- Original Message ----- From: xen-users-bounces@lists.xensource.com <xen-users-bounces@lists.xensource.com> To: xen-users@lists.xensource.com

Hi all, Curious issue.. looking in to how much disk space is being used on a machine (CentOS 5.3). When I compare the output of du vs df, I am seeing a 12GB difference with du saying 8G used and df saying 20G used. # du -hcx / 8.0G total # df -h / Filesystem Size Used Avail Use% Mounted on /dev/xvda3 22G 20G 637M 97% / I recognize that in most cases du and df

Hi all, I can't seem to get my fonts to look decent under CentOS. I was able to make them look pretty good under Ubuntu, but for the life of me I can't make them look decent on CentOS.

Hi, we bought some machines with 2 x quad core Xeon E5405 processors and installed centos 5.3 on them. My problem is that I can't get the cpuspeed service to work. No driver seems to claim responsibility for the throttling and the fallback "modprobe acpi_cpufreq" in the cpuspeed init script just yields a "No such device" message. According to the acpi information the

Hey folks, CentOS / PostgreSQL shop over here. I'm hitting 3 of my favorite lists with this, so here's hoping that the BCC trick is the right way to do it :-) We've just discovered thanks to a new Munin plugin http://blogs.amd.co.at/robe/2008/12/graphing-linux-disk-io-statistics-with-munin.html that our production DB is completely maxing out in I/O for about a 3 hour stretch from

Hi all, I have a PowerEdge 1950 that was acting weird. Network connectivity was only performing at a quarter of what was expected (if that). Even if I scp'd something to localhost it would perform poorly. Rather than fight with it, I just decided to reload it. It was running 5.3, and it is now running 5.4. However, when I go to boot it gets stuck at starting udev. If I let it sit

They're a ton of fun to tinker with too. I am also an old guy and didn't want to use the Rpi for this purpose. However, many years

Howdy, I recently went through a frustrating experience trying to get Xen 4 running on a CentOS 7 system. After a fresh install, fully updating the system, rebooting, then trying to install Xen4CentOS it would fail to boot into the 4.9 kernel, sitting there with a blinking cursor indefinitely. I thought it was a failure with grub, but it turns out this was set in the grub config:

I've been having an odd problem lately. When I drag files from the computer to a flash drive, they appear to copy, but when I try to use the files I find that only the name was copied (file size of 0). When I copy the same files to the same flash drive, from the terminal, everything seems to work. Has anyone else experienced a problem like this? It's starting to get a little frustrating.

Hi all, Annoying issue.. my ThinkPad T61 has an iwl4965 wireless card. When I have the wireless switch on, I experience a lot of issues.. system keeps freezing..unfreezing..freezing..etc. Sometimes, a soft lockup is logged to /var/log/messages. psmouse.c also sometimes throws an error saying the mouse lost synchronization. Obviously, this is causing the system to freeze for a sec and

Hello all, I am setting up freenx on a machine and I am able to connect to it remotely. However, when I connect and start xfce it does not appear to use the correct settings. It acts like it is a whole different user. It is starting the desktop environment as the nx user rather than myself. Is there any way to have the NX server connect as myself rather than having a whole separate

Greetings- The subject sums it up... I have a Dell 2950 acting as a general purpose 'storage' machine, handling some NFS work for some local servers, and also pulling in rsync backups of some largish filesystems over SSH. These backups, prior to the upgrade were taking about 6 hours to complete (MANY small files). Now, after the upgrade, the same backups are taking about 16 hours to

Hello, I have some problem with poor network performance on libvirt with qemu and openvswitch. I’m using libvirt 1.3.1, qemu 2.5 and openvswitch 2.6.0 on Ubuntu 16.04 currently. My connection diagram looks like below: +---------------------------+ +---------------------------+

There is a lot of talk about the vulnerable Linux kernel. I'm simply wondering the telltale signs if a given system has been hacked? What, specifically, does a person look for? Thanks. Scott

Hello, I have no queue configured on tap and veth devices, quest type is of course KVM and I’m using virtio model for VM’s NIC. What we found is that on Xenial (where performance is poor) during test ovs-vswitchd process is using 100% CPU and there are some messages in ovs logs: 2017-05-12T14:22:04.351Z|00125|poll_loop|INFO|wakeup due to [POLLIN] on fd 149

Hi, I have a problem with a dom0 which is unable to launch my domU : all my dom0 are Debian Lenny amd64 with Debian kernel 2.6.26-2-xen-amd64 and xen-hypervisor-3.2-1-amd64. Then all domU (PV) are Debian Lenny amd64 too, with vanilla kernel 2.6.29.6. So, this new dom0 can''t launch any domU which are working on an other dom0. Software is same on both dom0, and hardware is near the

I'm up for a cell phone contract renewal and am considering upgrading my handset. I looked at some devices at my local AT&T store but nothing really jumped out at me. I'm particularly interested in a cell phone that has a reliable ssh client, with ssh-agent and public key authentication abilities. Those of you who administer systems remotely, what mobile ssh client do you recommend?

A few months ago, I built a samba 4 DC on a RPi 2B v1.1 with Louis' packages. It's just like a normal Intel cpu based installation with a couple of minor exceptions. I built mine on Raspbian Lite. You'll have to add an additional user and give it sudo privileges.The network setup was like the older Debian 9 by simply adjusting /etc/network/interfaces. To add Louis' repo

Hello Andrey, I am testing a small AD DC setup with 65 users and would like to know if you've had stable experience with running DC and File Server on one server. My test server is Dell Poweredge 2950 with SAS hard drives and 16 GB RAM. So far everything runs normally with no high load and similar I/O on samba ports compared to the old standalone Samba 3 server I will be replacing. Thank
