similar to: using maxmem

Hello, We are going to buy some NFS storage for 6-8 VMs on a single host, but want to expand to a second host. What storage recommendations would you give if you have between 2000 and 5000 USD? How about nexenta? what hardware would you use? any vendor? Experiences with openfiler and opennas? Thanks for the responses. Daniel -- +-=====---------------------------+ |

Hi; Currently I am running xen 3.4.2 on one of my Centos servers , I want to upgrade to latest version of xen but I dont know if I should upgrade to latest branch of xen 3 or xen 4 ? is xen 4 backward compatible with xen 3 VMs ? does it provide any performance benefit compared to xen 3 ? What is your recommendation ? Regards

I am trying to allow domains'' memory allocation to be altered by using both the "memory" and "maxmem" options in my config files (i.e. set maxmem to some large value to allow the domain to be resized up to that amount, and memory to set the initial allocation). However I appear to lose potentially quite a large chunk of memory as I use a larger "maxmem"

There seems to be an outdated page to use PV drivers here: http://wiki.xensource.com/xenwiki/XenWindowsGplPv I''d be great if that could be updated. After installing the PV drivers in windows I didn''t notice any difference in performance at all. Windows says the drivers are working. Some more searching and reading and it appears that I do actually need to make some changes to

Howdy, I''ve read on http://revu.tauware.de/revu1-incoming/xen-0604251805/xen-3.0.2/docs/misc/xen_config.html about the maxmem option? What it do? I don''t see any result... I ''ve thought that the memory will automatically scaled to maxmem... but xm top show only 128 mb reserver for the guest machine also during high loads. greetings Fabian

Hello all, I''ve just installed a new dom0 with openSUSE 11.3 (x86_64) and I''m seeing domUs crashes when reading from disks. The problem occours when in domU configuration I use memory=1024 maxmem=2048 My setup is DRBD on LVM on Software RAID 10 and drbd devices are used as disks for domUs, using phy:/dev/drbd0,hda,w phy:/dev/drbd1,hdb,w The domU in test is HVM, I''m

Hello, I am using Xen 4.0.1 and Xen 3.2.1 dom0 with Debian Lenny and Squeeze dom0s. I have a bunch of virtual machines running , all using LVM as backend storage. Mostly, an LVM logical volume is mapped to a partition in the VM (eg: xvda1) I have tried to hot resize the filesystem in the VM without umounting it but it just do not work... Here is what I did: - lvextend on the dom0, -

I had temporarily started a VM, and it has allocated the memory for it. I have realised that after turning it down, the memory allocated to it, has remained reserved. Now, I need it for Dom0. So, how do I release the RAM that is reserved for VM, and make it available to Dom0? Is reboot the only option? _______________________________________________ Xen-users mailing list

Hai, I use following steps for LV backup. * lvcreate -L 5G -s -n lv_snapshot /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/VHD-a2db885c-9ad0-46c3-b2c3-a30cb71d83f8 lv_snapshot created* This command worked properly Then issue kpartx command kpartx -av

The changeset ''12803:df5fa63490f4da7b65c56087a68783dbcb7944f8'' added a new hypercall XENMEM_set_memory_map for specifying the e820 mapping. There was a small bug in the userspace side of this change though - the e820 mapping was specified based on the ''memory_static_min'' domain info parameter which means the memory map size is clamped to the value

I am trying to instantiate VMs with the maxmem parameter higher than the memory one. On the linux VMs it works fine, but on the windows VMs (windows server 2003 and 2008) the domU dont boot, they crash! And sometimes even the dom0 crashes. Can I set the maxmem on windows VMs?

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are

Hello, I was wondering if dovecot could help me in my project to smoothly make all my users switch to TLS encrypted POP / IMAP sessions and forget about cleartext. My first idea was to setup dovecot as a POP/IMAP proxy for my mailhosts and ask dovecot to display a warning message or slowdown non TLS sessions. Is there any way to achieve this with dovecot? Does anybody have another idea

On a 8 Core system only dom0 can set cap > 100 and vcpus > 1. On a domU ''xm sched-credit -d <domU> -c 200'' says "Error: cap is out of range". Vcpu cannot be set higher than 1 - regardless of boot/config/command line. Low performance is equivalent to the cap setting. See ''xm list --long'': (domain (domid 0) (uuid
