I''m installing a new server, and I want know waht is better: - Install xen from source from xen.org version 3.4.2 ? - Install xen fron apt-get from debian package 3.2.1 ? The server has Debian Lenny. What is correct on production server ? -- Martin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hello folks, I have a Xen server running on Centos 6.2 with 3.6.6-1.el6xen.x86_64 as the Dom0 kernel, and i have dedicted 2 CPUs and 4G ram for the Dom0.I have close to 4-5 Virtual machines running on the Xen server. The problem is that for some reason,carrying outany CPU/Disk intensive task on the Dom0 seems to be affecting the DomUs adversly.For ex.i noticed that my Domus become extremly

Hi All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

Package: xen-utils-common Version: 4.0.0-1 Consider removal of xenstored tdb file (located at /var/lib/xenstored/tdb) before start of xenstored daemon during the boot (or removal during the shutdown/reboot of the server) as proposed by Ian Campbell during our discussions [1].

Hi Guy, Anyone know how we can set up the vnc password during using virt-install command ? # virt-install \ --connect qemu:///system \ --name demo \ --ram 500 \ --disk path=/var/lib/libvirt/images/demo.img,size=5 \ --network network=default,model=virtio \ --vnc \ --cdrom /dev/cdrom

Hi, This patch intends to accurate vcpu weighting for CPU intensive job. The reason of this problem is that vcpu round-robin queue blocks large weight vcpus by small weight vcpus. For example, we assume following case on 2pcpu environment. (with 4domains (each domain has 2vcpus)) dom1 vcpu0,1 w128 credit 4 dom2 vcpu0,1 w128 credit 4 dom3 vcpu0,1 w256 credit 8 dom4 vcpu0,1 w512 credit 15

Sorry for posting again, but because the subject.Hi All, I have 5 servers each: Intel Quad Core i7 2.4Gig (8 processors)2 *1TB HDD2*1Gig NIC12G RAM I installed XCP 0.5 on each and all are joining a resource pool.Then I installed 2 Centos 5.5 VM on each XCP host and I used the following command to specify the number of vCPUs for each VM: xe vm-param-set uuid=$VM_UUID VCPUs-max=4xe vm-param-set

Good day. I found that XCP ignores VCPU-params (weight and cap) after VM live migration, as well, as those parameters ignored if changed on running VM. May I as someone with xcp cloud nearly check this bug? Thank you. -- wBR,George. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

So it didn't make any noticable difference in my test. I wonder if the test guest I'm using (Fedora 32 using dracut) doesn't use parallel compression? However I don't think it can cause a problem and it seems obvious that it could benefit some cases. Rich.

HI. Got a question. When I assign a number of vcpus to a DomU, Are they dedicated to that VM? For example: If I have 16 vcpus available and 8 DomUs, should I assign 2 vcpus for each one? or could I assign more vcpus (i.e. 6) and the hypervisor takes care of it?

When reducing the number of physical cpus available for Domain-0 by xl cpupool-numa-split, reduce the number of vcpus accordingly.

Hi, i'm playing a bit around with vcpus. My guest is Windows 10 1903. This is the excerpt from the config: ... <vcpu placement='static' current='2'>4</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no'/> <vcpu id='1' enabled='yes' hotpluggable='yes'/> <vcpu id='2'

My test box has an AMD dual core processor in it, giving me 2 physical cpu''s. If I overcommit the vcpu''s (eg vcpus=4) to simulate a 4 cpu machine, how accurate a simulation should it be (apart from performance sucking badly)?

Hi All, I am new here, please warn me If I am not following proper etiquette of this mailing list. I am breaking my head, regarding why libvirt is defining multiple CPU sockets when I increase the vCPU count. As and when I increase the vCPU count in libvirt guest XML, it is increasing the CPU sockets in qemu instance. " -smp 4,sockets=4,cores=1,threads=1 " instead " -smp

Hello, i have just migrated machine to xen server where only 2 cpus are available. I have copied config from machine where domU was located before. That machine had 4 CPUS (QUADCORE), current machine has 2 CPUS (1 XEON 2cores). I have forgot to change vcpus from 4 to 2 in config, but .. what really surprised me ... machine started . How it is possible? It was really slow alltought and not

Package: xen-hypervisor-3.2-1-amd64 Version: 3.2.1-2 Severity: normal I have a dual-core host. I wanted to give one of my guests use of 2 vcpus and use of both real cpus. I had the following in my config file for the guest: vcpus = 2 cpus = 0,1 This appeared to work correctly and I saw a big difference in the load average (the guest is monitored by munin-node). However after 12 hours or so,

Hi Daniel, Thanks a lot for the quick and detailed explanation. Please see my another query below. >>In normal usage, the guest vCPUs will be floating arbitrarily across any >>host physical CPUs.

Hi List, I have a server with two QuadCore 2.93Ghz processors and 16GB Ram, running Debian etch and Xen 3.2-1. Until yesterday I had in this server 2 hvm virtual machines, running w2k, 4 vcpus each without any problem, the use of each virtual machine rarely reach 70%. Today I cloned one of the virtual machines and started they with 2 vcpus, right after I start this new guest the use of cpus
