Hello,I've encountered a very weird problem. Some isos (Linux installers) freeze HVM dom0 and it is not possible to continue installation. dom0 runs on Debian unstable (it ran Debian Etch, but there was Xen 3.0.3 and I was sugested to upgrade to Xen 3.1 which is in unstable) and I have sucesfully created a few paravirtualized domU domains. I even sucesfully created HVM domain using debian netinstaller and I am able to boot it and use it. However recently I was told to install Fedora7 in fully virtualized environment and I failed. I've tried for two days and this is what I've found: It freezes at random manner. I've made a few snapshots which clearly show that sometimes i can see a line or two before it freezes completly[1]. The first two snapshots are taken when I was trying to boot R.I.P. liveCD distribution. The third one shows that debian-netiso works flawlessy - I am able to type boot commands and perform whole installation.

Pitty since the most (my) servers have Intel chips. But maybe there is some patch or workaround to create and use HVM on intels? poligon:~# xm info host : poligon release : 2.6.18-4-xen-amd64 version : #1 SMP Fri May 4 02:40:51 UTC 2007 machine : x86_64 nr_cpus : 4 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 2 threads_per_core : 1 cpu_mhz : 1600hw_caps : bfebfbff:20100800:00000000:00000140:0004e33d:00000000:00000001 total_memory : 4094 free_memory : 1 xen_major : 3 xen_minor : 1 xen_extra : -1xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailablecc_compiler : gcc version 4.1.3 20070812 (prerelease) (Debian 4.1.2-15) cc_compile_by : waldi cc_compile_domain : debian.org cc_compile_date : Fri Aug 31 08:20:38 UTC 2007 xend_config_format : 4 poligon:~# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU 5110 @ 1.60GHz stepping : 6 cpu MHz : 1600.088 cache size : 4096 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fpu : yes fpu_exception : yes cpuid level : 10 wp : yesflags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx tm2 cx16 xtpr lahf_lm bogomips : 4002.29 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: [...] poligon:~# cat /etc/xen/hvm.cfg import os, re arch = os.uname()[4] if re.search('64', arch): arch_libdir = 'lib64' else: arch_libdir = 'lib' kernel = '/usr/lib/xen-default/boot/hvmloader' builder = 'hvm' device_model = '/usr/' + arch_libdir + '/xen-default/bin/qemu-dm' memory = '512'disk = [ 'file:/home/xen/domains/ldap-hvm/disk.img,hda,w', 'file:/home/admin/kamyk/FC-6-i386-disc1.iso,hdb:cdrom,r' ] boot = 'd' vnc = 1 name = 'hvm' on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' /var/log/qemu-dm.*.log domid: 7 qemu: the number of cpus is 1 Watching /local/domain/7/logdirty/next-active qemu_map_cache_init nr_buckets = 10000 shared page at pfn 1ffff buffered io page at pfn 1fffd Time offset set 0 xs_read(): vncpasswd get error.
