similar to: Workaround for Xen HVM HLT-in-real-mode bug

Hello hpa, We are developing a Xen-based virtualization service, and we are trying to reduce excessive CPU utilization at isolinux boot prompts. When users boot up a virtual machine on an isolinux boot CD, the CPU starts spinning at 100%. These machines frequently get left in this state for days or weeks, degrading the service for everyone else. You replied to the work-around discussed in

Hello! I want to run windows in xen. My linux distrution in ubuntu 6.06 amd 64. I downloaded and installed xen 3.0.2 from binaries. I found that hvmloader is not included in binary distribution :-( So I try to compile it from sources. I get following error: cpp -P -DDEBUG -DTEXTADDR=0x000D0000 vmxassist.ld > vmxassist.tmp ld -o vmxassist -m elf_i386 -nostdlib --fatal-warnings -N -T

This patch adds "wbinvd" instruction emulation for vm86 mode. This is needed when we bring up AP of SMP VMX guest.

If anyone is still interested in this old thread, I have a rh7.3 image running under hvm. It''s a hack, but here''s what I did: Install rh7.3 in a vmware machine with vmware server.

Hello, I read in the announce of Xen 3.2.0 released that it has "preliminary support for a wider range of bootloaders in fully virtualised (HVM) guests, using full emulation of x86 ''real mode''" . I''d like to know what is the level of the emulation of x86 ''real mode''? I ask that because I tried to install OpenSuse 10.3 (I used the iso file

Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

A "main" function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c. In this main function, rombios, vgabios and vmxassist are copied to specified address, with following commands memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz); ... memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot)); ....

Hey, I have installed Ubuntu 8.10 with FV mode. I use this server for web server (command line mode only, no X window) So should I hack my current installation into a PV mode for production use? In fact, any min. performanc gain suppose I should get? (Any bechmark?) Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Dear List: The square of the noncentral t-statistic with noncentrality parameter \delta is a noncentral F with noncentrality parameter \lambda=\delta^2. So, t^2_{\nu,\delta} = F_{1,\nu,\lambda=\delta^2}. Consequently, it should follow that t^2_{1-\alpha/2,\nu,\delta} = f_{1-alpha,1,\vu,\lambda=\delta^2}. However, this is not what is happening with the following code. The central

Not yet, but I don''t see any reason for it to work any differently.
