Hello Xen users,
i''m using Xen 4.1.2 on Gentoo Hardened and i''m stucked with
one thing.
After starting my domUs, i would like to have them pinned to specified
CPU cores. I''m using this config file:
kernel = "hvmloader"
builder=''hvm''
memory = 2048
name = "VirusfreeDB"
vcpus=4
cpus="16-19"
acpi=1
apic=0
vif = [ ''bridge=xenbr0, script=vif-bridge, type=ioemu, model=e1000,
mac=00:16:3e:63:90:aa'' ]
disk = [
''phy:/dev/vg/VirusfreeDB,hda,w'',
'',hdc:cdrom,r''
]
on_poweroff = ''destroy''
on_reboot = ''restart''
on_crash = ''restart''
device_model = ''qemu-dm''
boot="dc"
sdl=0
opengl=0
vnc=1
vnclisten="127.0.0.1"
vncpasswd=''''
stdvga=0
serial=''pty''
tsc_mode=0
xen_platform_pci=0
so I suppose that it should be pinned to CPUs 16 to 19. But in ''xl
vcpu-list'' is ''Any CPU'', thus i have to do this
manually with ''xl
vcpu-pin'' command. Is there any way to do this automaticaly? Or am I
doing something wrong?
Let me know if you need any other information, I''m new here.
Thank you
Jan Hejl

Thank you so much Ian. I''ll wait for 4.2.0 to be released on Gentoo.

Hello I''m currently using Xen-4.1.2 and Linux-2.6.32.57 while looking in my dmesg output, i''m always having those errors: [VT-D]iommu.c:856: iommu_fault_status: Primary Pending Fault (XEN) [VT-D]iommu.c:831: DMAR:[DMA Read] Request device [02:00.5] fault addr 425541000, iommu reg = ffff82c3fff57000 (XEN) DMAR:[fault reason 02h] Present bit in context entry is clear (XEN) print_vtd_entries: iommu = ffff83043d6875b0 bdf = 2:0.5 gmfn = 425541 (XEN) root_entry = ffff83043d633000 (XEN) root_entry[2] = 275aa6001 (XEN) context = ffff830275aa6000 (XEN) context[5] = 0_0 (XEN) ctxt_entry[5] not present I don''t need VT-D. Is there a way to solve this problems! Cheers -- MAYAP Christine IRIT/ENSEEIHT 2 rue Charles Camichel - BP 7122 31071 Toulouse cedex 7
