Hi, My Xeon CPU spports lots of capabilities, when I cat /proc/cpuinfo, the flags list: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr dca lahf_lm. After a make world building of Xen-3.3.0, when I cat /proc/cpuinfo, the flags list only: fpu de tsc msr pae cx8 apic mtrr cmov pat clflush acpi mmx fxsr sse sse2 ss ht nx constant_tsc pni est. I am only able to make world the dom0 kernel, as I don''t know how to configure the kernel. Last time I make oldconfig, but it eventually failed. Can anyone help? I want to add at least the "vmx" CPU capability to dom0 kernel.

A lot of features are not usable by dom0 kernel and hence are hidden by Xen. -- keir On 24/11/08 13:15, "Y.

>A lot of features are not usable by dom0 kernel and hence are hidden by Xen.I got it. dom0 is just a domain, so it should not see _some_ features. This is reasonable. Actually, I am trying creating a hvm domain to install debian4 with an ISO file installer. I thought maybe the reason is that dom0 is not configured with vmx feature. According to your explanation, I was wrong. But what is the real problem? The system is xen-3.3.0 + dom0 generic pv kernel 2.6.18.8 with gnome. After I entered command: xm create dom.hvm.conf, the console outputs: Using config file "./dom.hvm.conf". Started domain dom3 Nothing else happened thereafter. I really don''t know what is wrong and what I should do. My hvm configuration is: import os, re arch = os.uname()[4] if re.search(''64'', arch): arch_libdir = ''lib64'' else: arch_libdir = ''lib'' kernel = "/usr/lib/xen/boot/hvmloader" builder=''hvm'' memory = 512 name = "dom3" vcpus=1 vif = [ ''type=ioemu'' ] disk = [ ''phy:sdb9,hda,w'', ''file:/xen/dom3/debian-40r5-i386-netinst.iso,hdc:cdrom,r'' ] device_model = ''/usr/'' + arch_libdir + ''/xen/bin/qemu-dm'' sdl=1 opengl=1 vnc=1 vncpasswd='''' stdvga=0 serial=''pty'' Thanks in advance, Shawn _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Something like ''vncviewer localhost:5900''. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
