[Xen-devel] Low performance and some problem with kernel 2.6.32.13 and xen 4.0-rc1
Server is Dell T610 with last bios (2.0.13) Dom0: Lenny 64 bit, kernel 2.6.32.13, xen 4.0-rc1 Kernel is last commit of jeremy git xen/stable-2.6.32.x with this config: http://old.nabble.com/file/p28704783/config-2.6.32.13 config-2.6.32.13 lspci -vvv: http://old.nabble.com/file/p28704783/lspcivvv.log lspcivvv.log dmidecode: http://old.nabble.com/file/p28704783/dmidecode.log dmidecode.log dmesg: http://old.nabble.com/file/p28704783/dmesg dmesg lsmod: http://old.nabble.com/file/p28704783/lsmod.log lsmod.log xend log: http://old.nabble.com/file/p28704783/xend.log xend.log menu.lst: title Xen 4 / Debian GNU/Linux, kernel 2.6.32.13 root (hd0,0) kernel /boot/xen.gz dom0_mem=2560M module /boot/vmlinuz-2.6.32.13 root=LABEL=root-backup2 ro nomodeset module /boot/initrd.img-2.6.32.13 The server run 12 domU windows xp with gplpv 0.11.0.213, all work On dom0 blktap not work (write about in other topic) and i must chage domU disk from tap:aio to file, is one or the problem about performance? With not set of dom0 memory and dom0 balloning have "freeze" with last msg calltrace about out of memory, i set dom0 memory in menu.lst and disable dom0 balloning, is necessary more ram that 2.5gb for dom0? There are some option in .config of kernel wrong or not good? with c state option in bios enable system is inusable, now i disable it but this is kernel, xen or bios problem?

Start with 1024 MB. You might be able to go down to 512 MB or so. It really depends what kind of tools you run in dom0. Also remember that file: driver for guest disks uses dom0 page cache, so it may appear that a lot of dom0 memory is used when using file: driver since dom0 page cache will use *all* the free memory.. so increasing dom0 memory just makes you use more of the memory as cache. You really should get tap:aio: working instead.

If yes, then you should definitely upgrade to Xen 4.0.0 final, or even better, to Xen 4.0.1-rc1. There was some dom0 memory corruption bug fixed around Xen 4.0.0-rc6.

Sorry, i wrong to write, is 4.0.1-rc1, i have always take from xen-4.0-testing.hg last weeks about xen 4 Yesterday i have try tap2:aio in cfg files and work, is blktap how not work with lenny, pv_ops kernel and xen 3.4.3 or 4.0 With tap2:aio minor ram used by dom0 but i see minor performance on domU (mainly on start) All important fix do in unstable are merged with xen-4.0-testing.hg?

Re: [Xen-devel] blktap2 problem with pvops kernel 2.6.32.13 and xen 4.0-rc1
I''ve attempted to install Nexenta Core 3 image under Xen 4.0 (2.6.32.13 pvops) on top of F13. Sample nexenta3.cfg profile contains 4 lines like this:- disk=[''tat:tapdisk:vhd:/path/../disk.img,xvda,w''] ( from sample) It generates message File ''vhd:/path/.../disk.img'' doesn''t exist. Boris. P.S.

Re: [Xen-devel] Low performance and some problem with kernel 2.6.32.13 and xen 4.0-rc1
Now i have update kernel to last of xen/stable2.6.32.x
DomU disk is with blktap2 (tap2:aio)
13 domU hvm (windows xp with gplpv 0.11.213) running
dom0 ram decrease to 1.5 gb:
------------------------
#free
total used free shared buffers cached
Mem: 1563136 1485024 78112 0 35960 1155452
-/+ buffers/cache: 293612 1269524
Swap: 2097144 0 2097144
------------------------
Some error show on boot mainly about ioapic and acpi, here dmesg:
http://old.nabble.com/file/p28765188/dmesg dmesg
What these messagges are related to? Kernel, xen or bios?
