Hi, I am using xen 4.0.1 from debian Squeeze repositories and dom0 has kernel 2.6.32-5-xen-amd64(also stock debian). I wanted to set a high value to maxmem in my xmdomain.cfg vm config files so that I can increase memory as needed without rebooting. Unfortunately as soon as I set this paramater I see really wiered things. For example, I am trying to install a windows HVM guest. When maxmem is not set, the first screen of the installer appear after l...

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" option. For instance if...

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 _______________________________________________ Xen-users mai...

As I understand concept of xenballooning, it allow to take memory from guest and return it to hypervisor. This allow to reduce amount of memory allocated to VM in realtime without rebooting VM. But how we can add more memory to guest VM in realtime, than was at boot time? Can we somehow make balloon inflated at start time? (F.e. VM starts with memory = 512Mb and balloon inflating to +512Mb).

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 using the openSUSE 11.3 rescue system for testing. drbd0 is 300Gb and is partitioned this way: Device Boot...

...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 ''memory'' config option. What we actually want is to setup the e820 map limit based on ''maxmem'' config option, so that we can balloon up the guest to its max limit. eg If we boot with ''memory=400'' and ''maxmem=800'', the e820 map should be set to 800 MB, and the guest should allocate only 400 MB at startup. It should then be possible to use...

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?

Hi there, I''ve read the paper on Xen live migration, and it shows some very impressive figures, like 165ms downtime on a running web server, and 50ms for a quake3 server. I installed CentOS 5 on 2 servers, each with 2x Xeon E5335 (quad-core), 2x Intel 80003ES2LAN Gb NICs. Then I installed 2 DomUs, also with CentOS 5. One NIC is connected to the LAN (on the same switch and VLAN), the

Hi, I have installed xen3.0.4.1 from source and every thing works well. Now I need to upgrade to xen-unstable. It is compiled and installed successfully (at least it seems to be) and I''m able to boot and run dom0. But Xend does not work. "xend start" gives no warning or error but running "xm list" I see: Error: Unable to connect to xend: No such file or

Due to IA64 balloon driver not ready and it depends on max memory value to allocate its memory. So this fix is necessary now.
